The hypothesis has come from previous studies on the subject, which broniatowski points like the root of confusion. "When you have that kind of thing, people are starting to rationalize," Well, maybe it should not get this second dose, "especially when they have other obstacles or other concerns," he says.

Kim agrees, especially since the Delta variant is now the dominant strain, which represents 58 percent of new infections, according to the CDC. "I also encourage people who have confirmed Covid-19 earlier to get vaccinated. There is more and more evidence that the natural infection by the initial strain is not very protective against Delta, "Kim saidDesert news. "Thus, the risk of pierced infection is very high. »

A R.U., which was published in May, but has not yet been examined by peers, found that after a dose, the Pfizer vaccine was 33 per centeffective against the delta variant in the prevention of symptomatic Covid. But after the second dose, this number climbed 88 percent.
