There is no risk of a new wave, but it is necessary to take a booster dose

Despite the signs of a rise in the number of cases and deaths from Covid-19, experts say that the forecast is that the country will not face waves of hospitalizations in the coming months.

To ensure safety, it is necessary to increase vaccination coverage of the third dose, which currently covers just over 41% of the population, and of the fourth dose among the elderly, which was applied to only 16% of the population over 80 years of age, according to the Ministry of Health.

“We have a high percentage with two doses, which is safe against hospitalization and death, but it is not ideal. We have a lot of people without the third and fourth dose who are most at risk. People aren’t going back to backup because they’ve lost the sense of urgency since we’re in this better scenario. But we know that, in a population that cannot reach a high percentage of vaccination, the disease continues to circulate and eventually reaches the most vulnerable”, said microbiologist Natalia Pasternak, president of the Instituto Questão de Ciência, to the newspaper O Globo.

“Accelerating vaccination is not something that happens overnight. So, we have to prepare ourselves to avoid problems two to three months from now, we need to take action now. It’s no use talking about it when we’re on a wave with an increase in numbers,” said geneticist Salmo Raskin, director of the Genetika laboratory in Curitiba, to the newspaper.

In Brazil, vaccination coverage is high among the elderly, reaching approximately 90% of those over 70 years old, but it is still low in other age groups. Among people aged 18 to 35 years, not even 40% received the application of the three doses and this impacts national protection.

Only 41% of Brazilians sought a third dose booster and, after the peak of Ômicron, the vaccination rate was reduced. The rate of daily applications of booster doses fell from 740,713 in January to an average of 176,938 doses applied per day in the last week of April, a drop of 76% in the vaccination rate.
