Ask an Expert: Why is a booster shot necessary?


You have asked: “Why would a booster shot be necessary if it’s just the same thing that I’ve already received?” This is such a good question.

I think it’s really important for you to understand that booster shots are not new in healthcare. I would suspect that many of you had had a booster shot in the past. Those might include hepatitis, HPV, tetanus, the annual influenza vaccine as well. With these older vaccinations, much research has gone into appropriate timing for the vaccine and typically how long the immune response will last. Although it certainly feels like COVID-19 has been with us for forever. The reality is that it’s very novel. And new research has been done daily to determine how strong and how long the immune response and protection will last for each vaccine that we get.

It’s important to also know that having to receive a booster vaccination does not mean that something is going wrong or that the first dose was not effective. It just means that science has learned something new and recommends further maintenance for your best health. Currently, we are waiting on recommendations from scientists and medical professionals on when to administer that booster vaccine.

So stay tuned with your primary care office for when that time comes.
