Debbie writes: “I heard there was a study that said the Modernna vaccine produced more antibodies than Pfizer. If I had the Moderna vaccine, would I still need to get a booster vaccine?”
There are some studies suggesting that the Moderna vaccine may trigger the production of antibodies to the coronavirus more than the Pfizer vaccine, for example. Maybe it’s because Moderna uses a larger dose or two doses are three versus four weeks apart with the Pfizer vaccine. However, this does not necessarily mean that one vaccine is more protective than the other, possibly both becoming less protective over time. For this reason, I think boosters would be recommended for people receiving both the Pfizer and Moderna vaccines.
Joanne in Quincy said she felt tired and her feet froze after her second COVID vaccine. “Is a booster likely to have the same effect?” she asks. It won’t stop me from taking it though. ”
I think it’s unclear whether you would have the same side effects from a booster shot as you did for your first doses. For example, some people who experienced the “COVID arm” after the first dose of the Moderna vaccine had a milder case or no experience after the second dose. I’m glad you’re planning on getting a booster no matter what. Talk to your doctor about your concerns.
Ann, “If I had breakthrough on COVID-19, would I get it again?” he asks.
If you have a breakthrough case, your body has probably produced more antibodies to the Delta variant, which should provide additional protection against re-infection in the near future. Does this mean you can never get infected again? Probably not, but we don’t know. Eventually, your immunity will likely start to decline again. Other variants that may evade immunity from vaccines or previous infections may emerge over time. And the coronavirus can keep returning every year, so we may need to get vaccinated every 1 to 3 years to protect ourselves from serious illness.
