Fewer individuals have gotten Johnson & Johnson’s one-dose vaccine than Pfizer or Moderna. That is partly as a result of it was out there within the US later than each mRNA vaccines, manufacturing points resulted in hundreds of thousands of wasted doses, and use was paused briefly in April after considerations over a hyperlink to a uncommon however severe blood clotting dysfunction (principally in ladies beneath age 50) that is not seen with the mRNA vaccines. 

Those that obtained the one-dose J&J vaccine, together with immunocompromised individuals, have been initially left in another country’s booster shot plans due to a scarcity of information on the one-dose vaccine. The booster rollout on the whole is a controversial one — members of the World Well being Group have known as on nations such because the US to sluggish the method of giving booster doses to people who find themselves already vaccinated as a result of a lot of the world stays unvaccinated in opposition to COVID-19.

Johnson & Johnson’s booster is identical dose as its unique vaccine. 

In truth, some individuals could go for an mRNA booster due to their elevated threat of a uncommon however severe complication of Johnson & Johnson’s vaccine. Ladies beneath age 50 are at the next threat for the blood-clotting dysfunction related to Johnson & Johnson’s vaccine and may “learn about different out there COVID-19 vaccine choices for which this threat has not been seen,” the CDC says. (These clots are extraordinarily uncommon however thought of severe as a result of they usually require completely different therapy than the clots that happen from issues comparable to taking contraception tablets or using on an airplane.) 

Importantly, this threat is not related to the Pfizer or Moderna vaccines.

In scientific steerage issued this week, meant to assist stroll eligible adults by means of selecting a booster dose, the CDC stated that sufferers with a historical past of Guillain-Barré syndrome ought to “talk about the provision of mRNA COVID-19 vaccines” for cover in opposition to the coronavirus.

Though knowledge on “mixing vaccines” within the US is proscribed, it is been finished for months in different nations, the place some people have acquired a dose of AstraZeneca (a viral vector vaccine like Johnson & Johnson) mixed with a dose of mRNA vaccine. Preliminary knowledge on mixing COVID-19 vaccines for boosters within the US discovered that whereas all three COVID-19 vaccines used as boosters for J&J recipients elicited robust responses, Moderna’s and Pfizer’s boosters elicited a lot stronger antibody responses — 76-fold and 35-fold, respectively — than a second dose of Johnson & Johnson (four-fold). Whereas spectacular, antibody response is not the total image of immunity. 

What if I am immunocompromised and obtained J&J? 

Immunocompromised individuals who acquired Johnson & Johnson and are “reasonably or severely immunocompromised” ought to get a booster of any COVID-19 vaccine at the least two months after the one dose. This is identical advice for everybody else who obtained Johnson & Johnson, however given that individuals with a suppressed immune system often aren’t in a position to mount as robust an immune response, it is particularly essential they search out a second dose of COVID-19 vaccine. 

Though only a few immunocompromised individuals possible acquired Johnson & Johnson in comparison with Moderna or Pfizer, those that did have been uncared for within the CDC’s preliminary advice for an additional dose for reasonably or severely immunocompromised people for lack of information. (Immunocompromised individuals have been eligible for his or her first dose of COVID-19 vaccine earlier than most of the people, which suggests they possible obtained Moderna or Pfizer, which have been out there sooner within the pandemic.) Final month, the CDC issued steerage that Moderna or Pfizer recipients who’re reasonably or severely immunocompromised could obtain a fourth shot or booster at the least six months after their third shot.
