As residents put together to roll up their sleeves for a 3rd, fourth and even fifth dose of COVID-19 vaccine, some could also be questioning: Do I would like to stay with the identical model, or is it secure to combine it up?
When it involves the brand new COVID-19 Omicron bivalent booster, the reply is, sure, you possibly can combine and match.
You can get both the Pfizer-BioNTech or Moderna model, no matter which providing you beforehand obtained.
“The best booster for you is the one that you can get — either the Pfizer or the Moderna can be used, and they can be mixed or matched,” mentioned Dr. Robert Kim-Farley, epidemiologist and infectious illness professional on the UCLA Fielding School of Public Health. “If there’s shortages of one, you should not have hesitancy to take the other.”
Mixing and matching
Say an individual has obtained three doses of the Moderna shot. Should they stick with Moderna or combine it up with a Pfizer booster?
The impact on the physique’s immune system needs to be related both approach, UC San Francisco infectious illness professional Dr. Peter Chin-Hong wrote in a tweet.
“It’s OK to mix and match Moderna and Pfizer,” Dr. Ralph Gonzales, affiliate dean for medical innovation and chief innovation officer for UC San Francisco, mentioned at a campus city corridor final week. “I just got my Moderna two days ago and it was an interesting experience. I definitely felt a stronger response with the Moderna — having had Pfizer before — but either combinations are fine.”
The U.S. Food and Drug Administration truly allowed mixing and matching of COVID-19 booster doses beginning final 12 months, after it allowed folks to get their first booster dose. Despite having the selection, although, lots of people ended up staying model loyal.
But others switched it up, both as a matter of desire, availability or suggestion. Many of those that initially obtained the single-dose Johnson & Johnson vaccine, for example, opted for Pfizer or Moderna come booster time.
What is subsequent
When some folks — these age 50 and up and the immunocompromised — turned eligible for a second standard booster shot earlier this 12 months, some determined to go together with the opposite model. Dr. Robert Wachter, chair of the UC San Francisco Department of Medicine, in April determined to go together with Moderna for his fourth shot after three consecutive Pfizers.
“I saw it as a toss-up,” he tweeted on the time.
The up to date Omicron bivalent booster shot is obtainable to these age 12 and up. Adults can select from both Pfizer or Moderna; adolescents age 12 to 17 are solely eligible for Pfizer.
L.A. County Public Health Director Barbara Ferrer mentioned there’s some expectation that the up to date booster can be out there for kids age 5 to 11 maybe as quickly as October.
Officials are urging folks to get the up to date booster, which they count on will scale back the danger of an infection. It’s known as a bivalent shot as a result of it’s designed to guard not solely towards the unique coronavirus pressure, but in addition the newest Omicron subvariants which have dominated the nation this summer time, together with BA.5.
“The bivalent boosters provide protection against the subvariants that are currently circulating at the highest levels, and they’re going to be one of our best tools in planning for a safe, healthier and happier fall and winter holiday season,” Ferrer mentioned Thursday.
