Covid-19 Vaccine Side Effects: Your Questions Answered

Every day around three million people are meeting in the United States Covid-19 vaccine. And every new job poses new questions about what to expect after vaccination.

Last week I told the readers that I should send them Questions about vaccination. Here are some answers.

Short-term side effects such as fatigue, headaches, muscle aches, and fever are more common after the second dose of both Pfizer-BioNTech and Moderna vaccines, requiring two shots each. (The Johnson & Johnson vaccine requires only one shot.) Patients who experience unpleasant side effects after the second dose often feel they have a bad flu and use phrases like “it flattened me”. Uses or “I was useless for two days” “During the vaccine study, patients are advised to go to work for a few days after the second dose if they need to spend a day or two in bed. .

Data collected from v-SecureAll are encouraged to use the application to track side effects after vaccination, showing increased side effects reported after the second dose. For example, about 29 percent of people reported fatigue after the first Pfizer-BioNotech shot, but jumped up to 50 percent after the second dose. Muscle pain increased from 17 percent after the first pill to 42 percent after the second. While about 7 percent of people got chills and fever after the first dose, it increased to about 26 percent after the second dose.

new York Times Interviewed several dozen In later days newly vaccinated. They reacted widely, ranging from symptoms with no response to symptoms such as uncontrollable tremor and “brain fog”. While these experiences are not pleasant, they are an indication that your own immune system is growing a powerful response to the vaccine.

One Analysis of security data The first 13.7 million Kovid-19 vaccine doses given to Americans found that side effects were more common in women. And severe reactions to the Kovid vaccine are rare, in almost all cases. Anaphylaxis, or fatal allergic reaction, Occurred in women.

Women are more likely to report side effects of the Kovid vaccine and report unpleasant side effects, as well as other vaccines. Women and girls may produce up to twice as many antibodies after receiving flu shots and vaccines for measles, mumps and rubella (MMR) and hepatitis A and B one. study It was found that in almost three decades, women accounted for 80 percent of all adult anaphylactic reactions to vaccines.

While it is true that women may be more likely to report side effects than men, there is also a biological explanation of the higher rate of side effects in women. Estrogen Can stimulate an immune response, While testosterone can blunt it. In addition, many immune-related genes are on the X chromosome, of which women have two copies and males have only one. These strong immune responses help explain why 80 percent Women suffering from autoimmune diseases. You can read more Here are the side effects of women and vaccines.

Side effects get everyone’s attention, but if you look at the vaccine clinical trials and real-world data, you will see that many people do not experience any side effects beyond any side effects. in Pfizer vaccine testAbout one in four patients reported no side effects. in Modern test, 57 percent of patients (64 or younger) reported side effects after the first dose – reaching 82 percent after the second dose, meaning that approximately one in five patients had no reaction after the second pill. Granted.

The lack of side effects does not mean the vaccine is not working, said a professor at the University of Pennsylvania and a member of the vaccine advisory panel for the Food and Drug Administration. Dr. Offit noted that during vaccine trials, a significant number of people did not report side effects, and even then tests showed that about 95 percent of people were protected. “It proves that you don’t have side effects to protect,” he said.

No one really knows why some people have too many side effects and others have none. We know that younger people mount stronger immune responses to vaccines than older people, whose immune systems weaken with age. Women generally have stronger immune responses than men. But again, these differences do not mean that you are not safe if you do not feel much after getting shot.

Scientists are still not sure how effective the vaccines are in people whose immune systems may be weakened by certain medical conditions, such as cancer treatment or HIV infection or because they are taking immune suppressing drugs. But most experts believe that vaccines still provide some protection to these patients against Kovid-19.

The bottom line is that even though different immune responses may differ, the data collected so far suggest that all three vaccines approved in the United States – Pfizer-Bayonet, Modern, and Johnson – are critical illness and Cidid-. 19 are effective against death.

You should not try to prevent discomfort by taking painkillers before taking the shot. The concern is that premeditating with pain relievers such as acetaminophen (Tylenol) or ibuprofen (Advil, Motrin), which can prevent hand pain as well as side effects such as fever or headache, can also blunt your body’s immune response. .

While it is possible that taking painkillers before your shot may reduce your body’s immune response, vaccine experts say you should not worry, and you should not try to take another shot. Studies of other vaccines suggest that premaxating may slow the body’s immune response to the vaccine, with your immune system still mounting a strong enough defense to fight infection. review of Study of more than 5,000 children Compared antibody levels in children taking painkillers before and after vaccination and those who did not. They found that the pain reliever had no meaningful effect on the immune response, and that children in both groups produced substantial amounts of antibodies after their shots.

The high efficacy of all Kovid vaccines suggests that even if taking Tylenol before the shot blunted your body’s immune response, there’s some fringed room, and you’re still well protected against Kovid-19 Huh. “You think you should be convinced that you have an adequate immune response that you will preserve, especially for vaccines that is good,” Dr. Said Offit.

“It’s OK to Treat Pain” Side Effects with a Painkiller, Drs. Offit said, but if you don’t really need one, don’t take it. “

While most experts agree that it is safe to take a painkiller to relieve discomfort after being vaccinated, they advise against taking it after a shot as a preventive or if your symptoms are manageable without it. The concern with taking an unnecessary painkiller is that it may blunt some effects of the vaccine. (In terms of the vaccine, there is no meaningful difference if you choose acetaminophen or ibuprofen).

During modern testing, approximately 26 percent of people took acetaminophen to relieve side effects, and the overall efficacy of the vaccine was still 94 percent.

The research And anecdotal reports suggest that people with pre-diagnosed Kovid-19 infection may have a more rapid reaction and more side effects after their first dose of the vaccine than those who were never infected with the virus. A strong reaction to your first dose of the vaccine may also be an indication that you were previously infected, even if you are not aware of it.

If you previously tested positive for Kovid-19 or had a positive antibody blood test, be prepared for a strong reaction to your first dose, and consider scheduling a few days of work, just in case. . Not only will it be more comfortable to stay home and recover in bed, the side effects of the vaccine may resemble the symptoms of Kovid-19, and your coworkers may not want to be near you anyway.

Studies suggest that one dose may be sufficient for those who have a previously confirmed case of Kovid-19, but medical guidelines have not changed yet. If you have received Pfizer-Bayonet or Modern Vaccines, you should plan to take your second dose even if you have Kovid-19. Skipping your second dose can cause problems if your employer or airline asks to see evidence of future vaccinations. If you live in an area where single-dose Johnson & Johnson vaccines are available, you can be fully vaccinated after just one dose.

Vaccines are effective against a new variant that originated in the UK and is quickly taking effect in the United States. But certain types of coronoviruses, particularly those first identified in South Africa and one in Brazil, appear to be more adept at dodging antibodies in vaccinated people.

While this sounds worrying, hopefully there is reason. People exposed to more resistant variants can still be protected from severe disease. And scientists have a clear understanding of the variants that they are already working on developing booster shots that will target the variants. Variants identified in South Africa and Brazil are not yet widespread in the United States.

People who are vaccinated should still wear masks and follow public health guidelines, but you should not live in fear of variants, Dr. Peter j. Said Hotez, dean of the National School of Tropical Medicine at Baylor College of Medicine in Houston. “If you are vaccinated, you should feel very confident about how safe you are,” Dr. Hotez said. “It is unlikely that you will ever go to the hospital or ICU with the Kovid-19. In time you are going to see a recommendation for a booster.”
