Second COVID vaccine booster now or wait for the new vaccine?

Someone asked me the other day whether she should get the extremely safe second COVID-19 vaccine booster now or wait for the new Omicron-adapted vaccines that are coming in the fall from Pfizer and Moderna. I didn’t know the answer, so I thought I would investigate. Maybe it will help you or someone you know with that decision too.

The actual answer is a bit complicated, but there appear to be some good, solid recommendations coming from people who are experts in containing this pandemic. Let’s take a look.

By the way, this old dinosaur got his first Moderna booster in October 2021 and received his second booster (this time Pfizer) in April 2022. I do practice what I rant about here!

The future of the COVID-19 pandemic — vaccines are still the key

We are heading towards the start of the third year of the COVID-19 pandemic, and many people want to know what the future holds. Will there be more variants? Will we need more vaccines? Will there be more dumb ideas about the disease?

Well, I’m not a pseudoscientist, so I not only don’t make, but also I certainly don’t believe in predictions about the future course of the COVID-19 pandemic. But I think I can write down some science-based thoughts of what we might see over the next few months.

Why do we need COVID vaccine boosters for the Omicron variant?

I have seen a few comments about the need for COVID-19 vaccine boosters before and after the appearance of the new Omicron variant. Of course, anti-vaxxers use this as a reason to deny the effectiveness of the vaccine. However, I’ve even seen pro-vaxxers misunderstand why boosters are needed.

Today, Pfizer announced that its preliminary studies showed that individuals who have received boosters produce about 25X more neutralizing antibodies against the Omicron variant than those who received the COVID-19 vaccine alone. This is awesome news with the caveat that this has not been peer-reviewed or published, it is just a report from Pfizer itself. In the hierarchy of vaccine research, it is pretty low until it is published in a medical journal.

I’m going to try to explain the reasoning behind the need for COVID-19 vaccine boosters against the Omicron variant. I hope it provides some science-based facts about boosters so that it might help you in discussions about the vaccine and new variant. I’m dividing my explanation into three broad areas, with the intent to make the science as clear as I can.

And just to remind everyone, I am fully boosted with the Moderna vaccine.

COVID-19 vaccine boosters FAQs – what you should know

Following the advice of the Vaccine and Related Products Advisory Committee (VRBPAC), the FDA announced that COVID-19 vaccine boosters can be given to those individuals who received the Moderna and JNJ vaccines. This follows a previous announcement about the Pfizer vaccine booster shots. The FDA also stated that all eligible individuals could mix and match vaccines for their booster dose.

There is a lot of information about these boosters out there, so I thought I would take a moment to try to provide some facts and clarity about what the recommendations are about these COVID-19 vaccine boosters. Also, this is related to a US FDA set of decisions and recommendations from the CDC, so this article is going to only apply to the USA. However, don’t be surprised if the EU and other regulatory agencies across the world do the same thing.
