Can You Still Catch Virus After First Dose? – CBS Pittsburgh – Pittsburgh, Pennsylvania

(CBS Boston) — Currently, two COVID-19 vaccines are available in certain segments of the American population. One was released by Pfizer and the other by Moderna. Both need to be given twice at 3-4 week intervals, and both are ultimately about 95% effective.

Initially, the federal government stated that only healthcare professionals and residents of nursing homes should be eligible for vaccination. However, as of last Tuesday, people over the age of 65 or 16 and in an existing state have been added to the list. Individual states eventually make their own decisions, and some states are beginning to include teachers and first responders.

The first deployment is going slower than everyone wanted. According to the US Centers for Disease Control and Prevention, as of last Monday, 25 million doses had been shipped to hospitals and pharmacies. However, 9 million of those doses have not been administered.

Scheduling issues at the state level are also partly due to the pace of inoculation. Another possible obstacle in the future is public confidence in the new vaccine. According to a national survey conducted by the University of South Florida, 33% of respondents said they were “not very confident” or “not confident at all” that the recently approved vaccine was safe. In addition, 23% said they were “probably not vaccinated” or “never vaccinated”.

Accelerated deployments carry many questions. CBS Local provided reader and viewer questions to experts Dr. Marika Marshall and Dr. Max Gomez. Dr. Marika Marshall is an Emmy Award-winning journalist and physician and a regular health reporter on WBZ-TV in Boston. Dr. Max Gomez is a medical reporter at WCBS-TV in New York.

Talk to your doctor before making a decision about your personal health, while both Marshall and Gomez offer the best advice.

Is it safe to get the COVID vaccine if I have responded to the flu vaccine in the past?

Marshall: Yes. Coronavirus vaccines can be given even if there is a serious reaction to other vaccines, but they will be monitored for a long time after vaccination. Usually 30 minutes instead of the standard 15 minutes.

Can I get a COVID after the first vaccination?

Gomez: The simple answer is yes, but it’s not as frequent or easy as it was before the first dose. Pfizer clinical trials have suggested approximately 50% protection after the first dose. A new study in Israel found a decrease in new cases after the first dose. It’s something, but it’s not perfect. It takes several weeks after a lot of immunity develops on the first shot.

Yes, you will have to keep wearing the mask as you will be able to get a COVID until both doses are complete.

All this has one good news. According to the CDC, influenza activity remains lower than normal during this period. This is probably because people wear masks, keep a social distance, and wash their hands frequently. So keep it going-we don’t want the twin epidemic.

Every time I see them vaccinated with a coronavirus vaccine, I’m amazed at how long the needles look. Is it longer than most needles on other shots?

Marshall: The vaccine needs to be given to the deltoid muscles of the upper arm, so 1 to 1½ inch needles are used, depending on the size of the patient. This is the same as the recommended stylus length for influenza vaccines.

What is included in the vaccine?

Gomez: One viewer is very allergic to penicillin. Allergic reactions to the Pfizer vaccine are negligible, but neither vaccine resembles penicillin. Both the Pfizer and Modana vaccines use similar, entirely new technologies to induce immunity, so people naturally want to know what they contain. ..

Surprisingly few. There are small pieces of what are called messengers or mRNAs. This is a genetic blueprint that the virus uses to help corona-infected cells and make spike proteins that stimulate immunity. However, the vaccine does not contain coronavirus.

Another component is the small oily nanoparticles that surround and protect the mRNA. Otherwise, it will break down very quickly in the body. that’s it. No preservatives are used until it is mixed with sterile saline just before injection.

The government is currently releasing all shots – Round 2 isn’t coming up anymore – If you get the first dose, but for some reason you can’t get the second dose – What happens? Do I have to wait for a period of time before getting the next Round 1?

Marshall: A study with the Pfizer and Moderna vaccines considered giving a second dose 3-4 weeks after the first dose, so how would the effect change if you wait much longer? I don’t know. WHO states that you should not wait more than 6 weeks between doses, but the CDC states that you do not need to repeat the first dose if there is a delay. And there are other vaccines in the pipeline that may be approved in the coming months with a single dose.

What if you have a COVID, don’t know it, and now you have an antibody? Do I still need to be vaccinated? Is it safe?

Gomez: If you have a mild or asymptomatic COVID case, you may have developed an antibody against the coronavirus. Experts say it should protect you for a while. But don’t expect more than 90 days. So you don’t need a shot right away, but you still need one.

The CDC says it’s safe to vaccinate if you have antibodies, so you don’t need an antibody or COVID virus test before vaccination.

However, if you have COVID symptoms, the CDC says you should wait until all the symptoms are gone before firing.

Can the vaccines be mixed and combined? Shots from Moderna and Pfizer, or vice versa?

Gomez: Unfortunately, I really don’t know the answer. This is because these combinations have never been tested. At least not yet.

Theoretically, the two vaccines can be mixed and matched because they contain the same coronavirus gene sequence to stimulate immunity. The only difference between Moderna Shot and Pfizer Shot is the small lipid nanoparticles that surround the fragile mRNA gene.

However, at this time, due to the shortage of vaccines, it is unlikely that everyone will have one for each vaccine. The site that gives you your first dose should prioritize you for the second dose of your booster, so get whatever you can.

When my whole family is vaccinated, can we be with each other without a mask, and is it safe to be with our little grandchildren?

Marshall: It is not yet known if full vaccination can prevent the virus from infecting others. Better ideas will come in the coming months. In the meantime, even if vaccinated, you should keep a physical distance and wear a mask when you are around an unvaccinated person.
