The WHO (World Health Organization) reported on Thursday (9) that the immunity provided by vaccines against Covid-19 extends for up to six months after the second dose applied, or the single dose, as in the case of Janssen.
“We have reviewed the data that exists, and most show that immunity lasts for up to six months,” WHO Director of Immunization, Kate O’Brien, said at a news conference.
The group that advises the agency on immunization issues today issued the conclusions of the data analysis carried out in the last two days, but said it was too early to comment on the Ômicron variant of the new coronavirus and on the response of vaccines to the strain, which had detection announced two weeks ago.
The EMA (European Medicines Agency) said on Thursday (9) that most cases caused by the Ômicron variant of the coronavirus in the European Union appear to be “mild”.
“The cases appear to be mostly mild, but we have to gather more evidence to determine whether the spectrum of disease severity caused by Õmicron is different from that of all the variants that have circulated so far,” said the head of vaccine strategy. of the EMA, Marco Cavaleri.
The WHO (World Health Organization) said on Wednesday that the rate of Ômicron reinfections appears to be higher, but the variant causes less severe symptoms.
“Right now, we don’t have enough data on the impact of this variant on the effectiveness of approved vaccines, but we are continually looking to the horizon for results in this regard,” Cavaleri added.
The EMA has so far approved four vaccines and two antibody treatments and has given the green light to emergency use of the pill developed by the MSD laboratory.
