Boosters can be mix and match, which one is right for you?

 Well done to those of you who waited the 2 weeks I recommended, so we could get the rest of the facts on the boosters before making a decision.

Knee jerk reactions to “breaking news” really is no way to manage your health!

Now you and your physician can choose what is best for you, with all the data available, always the best strategy.

Here are some basic guidelines.
If you feel that you need more information or just want to sit down and discuss your particular situation please feel free to make an appointment.

I could have paraphrased the article below but I did not because I think it is very clear and self explanatory.

 At the end of the day I would say that in general, if you want to take an mRNA booster choose Moderna because it lasts longer. It doesn’t matter which vaccine you got the first time.
I still lean towards vector borne vaccines for young children even though they haven't yet received the EUA for this.
If you got a J and J vaccine go ahead and get the second one.
Last, but not least, it is not really clear when the Moderna vaccine needs to be boosted especially without underlying conditions. I think the 6 month recommendation was somewhat arbitrary and more based on the need for a Pfizer booster after 6 months.

“FDA Authorizes Boosters for Moderna, J&J, Allows Mix-and-Match” (Medscape article)

The US Food and Drug Administration (FDA) has authorized booster doses for the Moderna and Johnson & Johnson COVID-19 vaccines, while also allowing boosters to be given interchangeably with any of the other vaccines, in people who are eligible to get them.
The move to amend the Emergency Use Authorization for these vaccines gives the vaccine experts on the Centers for Disease Control and Prevention's Advisory Committee on Immunization Practices latitude to recommended a mix-and-match strategy, if they feel the science supports it. 
The committee convenes tomorrow for a day-long meeting to make its recommendations for additional doses.
People who've previously received two doses of the Moderna mRNA vaccine, which is now called Spikevax, are eligible for a third dose of any COVID-19 vaccine if they are 6 months past their second dose and are:
  • 65 years of age or older
  • 18 to 64 years of age and at high risk for severe COVID-19 because of an underlying health condition
  • 18 to 64 years of age and at high risk for exposure to the SARS-CoV-2 virus because they live in a group setting, such as a prison or care home, or work in a risky occupation, such as healthcare
People who've previously received a dose of the Johnson & Johnson vaccine are eligible for a second dose of any COVID-19 vaccine if they are over the age of 18 and at least 2 months past their vaccination.
"Today's actions demonstrate our commitment to public health in proactively fighting against the COVID-19 pandemic," said Acting FDA Commissioner Janet Woodcock, MD, in a news release. "As the pandemic continues to impact the country, science has shown that vaccination continues to be the safest and most effective way to prevent COVID-19, including the most serious consequences of the disease, such as hospitalization and death.
"The available data suggest waning immunity in some populations who are fully vaccinated. The availability of these authorized boosters is important for continued protection against COVID-19 disease."

On a different note:

Should you get a booster for Covid and which one?

 The booster situation is becoming clearer by the day.

For people who got the Pfizer vaccine and are 6 months out from their second shot, it is recommended they get a booster especially if they are immunocompromised or over 65. Studies have shown that with the Pfizer vaccine the antibodies to Covid go down precipitously by month 7, in some cases to undetectable.

Moderna has not been approved for a booster yet but I suspect that it will within the next week or two.
I am not allowed to make this recommendation yet because the FDA has not yet approved the Moderna booster but when they do, I am going to recommend that people who got the Pfizer vaccine consider getting the Moderna as a booster.
Moderna clearly has stronger protection and may eventually lead to less shots than Pfizer.

Not surprisingly people who got the Johnson/Janssen vaccine are going to need a second shot. The idea of the one shot deal turned out to be too good to be true.
The good news is that the second J and J shot takes immunity up to 95%. Which makes it even better than some of the 2 shot vaccines.

Here is an interesting commentary which I agree with:


The office will be open on October 11th which was the Columbus day holiday but has been renamed Indigenous Peoples day.

My office will also be open this Saturday October 9th.
