Just to clarify, the second dose for the Moderna and Pfizer vaccines are not boosters, but rather the second of 2 doses of the same vaccine, right? It's not really a booster.
And yeah, if a different vaccine has to be developed for the variant, it wouldn't be a booster but rather a full dose or regimen for the variant. So another Covid vaccine.
I appreciate the tip because when I was reading booster, I was thinking to myself that the term was probably not correct.
The second shot is a booster. They go hand-in-hand and to achieve 'full vaccination' you should get the second one, but the first delivers the mRNA instruction that jump starts the immunity process, and the second delivers the booster to make it last.
Vaccines are one of the biggest public health achievements in the last century. And the COVID-19 vaccine will be added to that list. The two FDA-approved COVID-19 vaccines, Moderna and Pfizer-BioNTech, require two doses to achieve immunity: a prime shot and a booster shot.
The first two vaccines to earn authorization — those developed by Pfizer and its German partner, BioNTech, and Moderna — use messenger RNA (mRNA) to instruct the body to build the coronavirus’ signature spike protein. The body then produces antibodies to combat the Coronavirus when it enters the body.
The first dose helps your body create an immune response, while the second dose is a booster that strengthens your immunity to the virus.
COVID-19 Vaccine: What You Need to Know About the Second Dose
As the COVID-19 vaccine rollout ramps up, you might be wondering why the mRNA vaccines are a two-dose series. The first dose helps your body recognize the virus and start an immune system response, while the second dose is a booster that strengthens your immunity to the virus.
