Drug use may increase the risk of Kovid-19 breakthrough infection


Breakthrough Infection: If you are a frequent use of tobacco or marijuana, if you are addicted to alcohol or drugs, you are at higher risk of contracting the corona virus despite a ‘breakthrough’ infection or complete vaccination. This disclosure has come from research published in World Psychiatry. The researchers concluded after analyzing 580,000 people who had taken both doses of the vaccine in the US.

Intoxication can increase the breakthrough infection of Kovid-19

Research has found that drug abusers are at a higher risk of getting infected with the corona virus even after using both doses of the Kovid-19 vaccine. Drug abuse disorder also known as drug addiction is a type of disorder i.e. dependence on marijuana, alcohol, cocaine, narcotic substances and tobacco.

Drug addiction reduces the effect of the vaccine

Researchers say that the effect of the vaccine in drug addicts may be reduced by excessive use of marijuana, alcohol, cocaine, drugs and tobacco. He wrote, “Addicts are at higher risk of COVID-19 infection and adverse consequences of infection. Although the vaccine is highly effective against COVID-19, the vaccine’s effect in drug addicts is due to a weakened immune system.” may be less than that.”

Research showed that 3.6 percent of non-drug addicts were affected by breakthrough infection while in contrast 7 percent of people with drug addiction were affected by breakthrough infection. Researchers said that people consuming marijuana were at the highest risk, ie 7.8 percent showed breakthrough infection. At number two, 7.7 percent of people who used cocaine were involved and 7.2 percent of people who used alcohol had a breakthrough infection.

Marijuana proponents said that the research did not see that marijuana could be the reason behind the breakthrough cases. Significantly, the results of the research have come at a time when the World Health Organization has recommended the use of the third dose of Kovid-19 vaccine to those with weakened immune systems. A panel of experts from the World Health Organization is going to review the global data on booster doses in a meeting to be held on November 11.

How dangerous is the delta variant for pregnant women who do not get the corona vaccine?


Delta Variant: A recent research has found that the delta variant can increase the risk of complications among women who are not vaccinated. Researchers analyzed severe illness of Kovid-19 in pregnant women from May 2020 to September 2021. Research has found that the corona delta variant is highly contagious.

Vaccination advice for pregnant women against Kovid

According to research published in the American Journal of Obstetrics and Gynecology, Kovid-19 was confirmed in 1515 pregnant women. Of them, 82 had serious cases and 11 required ventilator support. During this two pregnant women died. Research indicated that 5 percent of pregnant patients fought the serious disease of Kovid-19 by March 2021. Researchers say that pregnant women who have not been vaccinated are worried about their future.

Corona’s delta variant can increase the risk of problems

The research concluded that pregnant women after confirmation of the delta variant are more likely to develop serious disease and those who have not been vaccinated are at higher risk of hospitalization. Researchers urged pregnant women to get vaccinated because it is the best way to prevent Kovid-19. Last week the Centers for Disease Control and Prevention issued a warning asking pregnant women or those trying to become pregnant to get vaccinated against Kovid-19.

According to the CDC, as of September 27, more than 125,000 pregnant women have confirmed cases of Kovid-19. Of them, 22,000 had to be hospitalized due to severe infection and 161 died during this period. Despite the serious risk, the CDC reports that 31 percent of pregnant women aged 18-49 completed vaccination against COVID-19. The CDC wrote in its health advisory, “Pregnant women with symptoms of Kovid-19 have twice the risk of going to the ICU and the risk of death is increased by 70.”

What should pregnant women do after receiving the Covid-19 vaccine? – VnExpress


Pregnant women should not be alone in the first three days after injection, strictly monitor their health, create psychological comfort for the best immune response.

Pregnant women are considered a special target group when receiving the Covid-19 vaccine. The pregnant woman’s body has to bear the double burden; The kidneys, liver, cardiovascular and respiratory systems work with greater intensity. After the injection, they experience the same side effects as normal people such as fever, fatigue, headache, chills, joint pain, increased pain sensation, swelling, redness, restlessness, etc. Pregnant women need to be very careful, monitor and treat promptly if there are severe side effects.

Master, Doctor Vu Nguyet Anh, Deputy Head of General Planning Department, Hanoi Obstetrics and Gynecology Hospital, recommends that the first three days after vaccination against Covid-19 pregnant women should not be alone because this is the body’s time. Side effects are often present. Pregnant women actively monitor their own health, eat nutritiously, get enough sleep, and feel comfortable to have the best immune response after vaccination.

If the fever is below 38.5 degrees after injection, loosen clothes, apply/wipe with a warm towel on the forehead, armpits, groin, drink enough water, do not catch cold, measure the temperature again after 30 minutes. If the fever is 38.5 degrees or higher or body aches, pain at the injection site, take antipyretic, ordinary pain reliever containing paracetamol according to the instructions of medical staff. In case the fever does not reduce or the fever is higher than 39 degrees, the pregnant woman should immediately notify the medical staff and go to the nearest medical facility.

In case of swelling, redness, pain, small lumps at the injection site, monitor health. If the swelling is bigger, the symptoms do not decrease, the pregnant woman should go to the doctor immediately. Do not apply, apply on painful swelling at the injection site of poultices from herbs, leaves or ointments…

Pregnant women with a schedule of tetanus and measles vaccinations should arrange to have them at least 14 days before the Covid-19 vaccine or 28 days after the Covid-19 vaccine.

Vaccination of 1.6 crore people completed in Karnataka, know the condition of rest of the states of South India


Karnataka has defeated South Indian states in the measures being taken to prevent corona infection. He has completed the vaccination of the largest number of people against Kovid-19. Out of the targeted population of 4.9 crore, 16 crore (32 per cent) people have got both doses of the vaccine. This was revealed on Monday morning from the data of the Covin Dashboard.

Karnataka beats southern states in terms of complete vaccination

According to the data, Karnataka ranks fifth in terms of people who have been fully vaccinated. States like Maharashtra, Uttar Pradesh, Gujarat and West Bengal are ahead of Karnataka in the country. The number of people who got the doses of both the vaccines in Maharashtra is 2.2 crore, in Uttar Pradesh 1.8 crore, in Gujarat 1.8 crore and in West Bengal is 16 million. In terms of proportion, Gujarat’s role (37 per cent) is better than Karnataka, while Maharashtra (24 per cent), West Bengal (23 per cent) and Uttar Pradesh 12 (per cent) are at the bottom of the line. If we look at the figures of people who have completed vaccination in the southern states, it is found that in Andhra Pradesh about 13 million people have taken both doses of the vaccine, in Tamil Nadu 1.1 crore and in Kerala 10 million people have completed the vaccination.

Out of 4.9 crore, 1.6 crore people got both doses of the vaccine

In Telangana, 67.4 lakh people have been protected from both doses of the Kovid-19 vaccine. Arundhati Chandrashekhar, Mission Director, National Health Mission, Karnataka said, “We are yet to cover 67 per cent of the target population in Karnataka with the second dose. The focus is now on covering the rest of the population for the second dose in the state and this In this connection, we are sending messages to take advantage of the facility of free vaccination. We are planning to run a special campaign and focus on the backward districts in vaccination. Senior health department officials said that to reduce the severity of the third wave, maximum people should be fully vaccinated with both doses.

Do Corona Variants Reduce Protection Against Kovid? Know the importance of research


Variants of the corona virus ‘substantially’ reduce protection against vaccine or natural infection. This is to say the scientists of Oregon Health and Science University. Researchers tested two new strains of coronavirus, B.1.1.7 and B.1.351, on blood samples from those who were vaccinated or defeated Kovid. The B.1.1.7 variant of the corona virus was identified in the UK, while the B.1.351 variant was detected in South Africa and both were called variants of concern.

Variants of Corona reduce antibody level

Researchers say that the corona virus is constantly changing itself so that it can expand its spread. Lab research showed that Delta, a new type of corona, reduced virus-neutralizing antibodies in the blood serum of 100 people who had received or were previously infected with Pfizer’s vaccine. In the case of the beta variant, the researchers found a 9-fold reduction in antibody levels compared to the original corona virus. He also said that vaccination and prior infection provide a great deal of protection to the body against two new varieties of corona.

Need of booster dose also mentioned in future – Research

For research, he obtained new varieties of corona from patients and mixed each variant sample in volunteer’s blood sample and tested the effect of antibodies against the original corona virus. The results showed that the level of protection provided by the virus against the variants was low, especially in people aged 50 years and older. He said that the increase in risk in the elderly is worrying and there is a need to try to protect against the virus even after vaccination.

He said the results indicate that Pfizer’s vaccine retains some degree of protection against the variants, even if the level of neutralizing antibodies to the virus is reduced. Research results are generally consistent with recent reports. According to research, the results mean that booster doses may also be needed in the future, just like the annual flu vaccine. The results of the research have been published in the journal Nature Communications. Researchers said that the results show the importance of face masks and social distancing along with vaccination.

The milk of the mother who takes the vaccine makes antibodies, the child can be safe from Kovid – Research


Breast Milk: The milk of a mother who has been vaccinated for protection against Kovid contains antibodies that fight against the disease. This has been revealed in new research from the University of Florida. Research has shown that vaccination markedly increases the level of antibodies in breast milk against the corona virus that causes the disease of Kovid-19, which suggests that vaccinated mothers can pass immunity to their children.

Antibodies are formed in breast milk after vaccination

Researchers say that research was done to confirm this. When babies are born, their immune system is developing, due to which their fight against infection becomes difficult. Innocents are often too young to respond adequately to a particular vaccine. Breastfeeding mother’s milk provides the ability to protect the baby during this period of weakness.

According to researchers, vaccination is like a tool that becomes part of breast milk, which has the ability to prevent Kovid-19. He said that research provides a strong indication that the vaccine can help protect both mother and child, which is a solid reason to vaccinate for mothers who are pregnant or breastfeeding. The research was carried out between December 2020 and March 2021, when Pfizer and Moderna’s vaccines were first made available to health care workers. Researchers included 21 healthy breastfeeding health care workers who were not infected with corona.

Result extracted from mother’s milk and blood sample

The team took samples of the mother’s milk and blood thrice, once before vaccination, once after the first dose of the vaccine and lastly after the second dose. “We observed strong antibody responses in breast milk and blood samples after the second dose, which was a 100-fold increase compared to pre-vaccination,” the researchers said. He told that the level of antibodies was also very high in the mother infected with the corona virus. The results of the research have been published in the journal Breastfeeding Medicine.

Vaccinated people reduce the risk of nCoV infection by three times


New British research shows that people who get two doses of the vaccine are three times less likely to be positive for nCoV than people who have not been vaccinated.

The study by the Covid-19 surveillance program REACT-1, led by Imperial College London and Ipsos MORI, was based on analysis of test results of more than 98,000 people between June 24 and July 12. The results showed that unvaccinated people had a three times higher risk of infection than people who received full doses, with a rate of 1.21% and 0.4%, respectively.

The study added that if fully vaccinated people contract nCoV, they also have a lower risk of transmitting the virus to others, due to their small viral load.

“These findings suggest that two doses of the vaccine provide a good layer of protection against infection,” said Professor Paul Elliott, School of Public Health at Imperial College London.

In more than 98,000 test samples, scientists recorded 527 positive samples, equivalent to 0.63%. This number increased four times compared to the report published on June 17, made from May 20 to June 7, with a rate of 0.15%. The highest rate of viral infections was recorded in London, with 0.94%.

The results of gene sequencing of 254 out of 527 samples resulted in infection with the Delta variant. Warning about the threat from Delta, scientists say that even if restrictions have been eased, people should still act with caution to avoid the risk of nCoV infection and community transmission.

How important is the mask after taking both doses of the vaccine, know the opinion of experts


No clear rules on masks for both doses 
In many parts of the US, it has been allowed not to wear masks after taking both doses of the vaccine. Due to people doing this on a large scale, California again issued an order to apply masks. However, the US Centers for Disease Control and Prevention has not yet taken a similar approach. National Nurses United has called on the CDC to reconsider. Peter Chin-hong, an infectious disease specialist at the University of California, has said that there is clear evidence that Kovid-19 can be transmitted even after full vaccination. The CDC is studying these figures closely. Therefore, as a precaution, people should wear masks. However, no guidelines have been issued regarding the wearing of masks for both doses. 

First dose delta variant at risk
In the US, 60 percent of the population over the age of 18 has been fully vaccinated. But everyone has doubts about the Delta variant. Preliminary data suggests that increased exposure to delta-like variants may increase the risk of infection in people who have received the first dose of the vaccine. For example, one study found that a single dose of the Pfizer vaccine had only 34 percent effectiveness against symptomatic disease compared to the delta version, compared to 51 percent in the older alpha version. On the other hand, according to data from Scotland and many other countries, the Pfizer vaccine after two doses provides strong protection against the delta variant. In preliminary studies in Canada and England, researchers found 93 percent effectiveness against the alpha version and 88 percent against the delta version.

Experts call unvaccinated people a ‘mutation factory’


Infectious disease experts warn that people who have not been vaccinated against Covid-19 can become a breeding ground for new strains of the virus.

“Unvaccinated people are potential mutation factories,” warns Dr. William Schaffner, professor in the Department of Infectious Diseases of Vanderbilt University Medical Center, Tennessee, USA. “The more people who are unvaccinated, the more chance the virus has.”

Schaffner said that the infected person’s body is the environment for the virus to constantly mutate and can produce more dangerous mutations than the original.

Although most mutations have no effect on the virus and some can even weaken the virus. But sometimes, mutations will create a variant that is more contagious or capable of infecting many different hosts.

“When mutations occur in viruses, persistent mutations often make it easier for the virus to spread in the community,” said Andrew Pekosz, a microbiologist and immunologist at the Johns Hopkins Bloomberg School of Public Health. to speak. “Every time viruses mutate, they have different platforms to spike.”

The mutations would make the virus more deadly than the original strain that emerged in China. The Alpha variant, or B.1.1.7, became the dominant strain in the US late last spring due to its ability to spread easily. But the current Delta variant is even easier to infect and is expected to become the dominant strain in many countries, including the US.

Available vaccines can still protect people against current strains, but experts warn this could change at any time if the virus continues to have a chance to mutate. That’s why doctors and public health officials are urging many people to get vaccinated quickly.

“The more we let the virus spread, the more chance the virus has to mutate,” the World Health Organization (WHO) said last month.
