Finicky “vaccine sommeliers” undermine Brazil inoculation campaign, experts say

RIO DE JANEIRO, BRAZIL – One question rippled through the queue outside a makeshift inoculation center in Rio de Janeiro’s beachside neighborhood of Copacabana on a recent morning: “Which vaccine are they using?”

Despite the world’s second-highest death toll and infections running high, some people across Brazil are refusing to receive their shot if the vaccine being used is not to their satisfaction. Local media have dubbed them “vaccine sommeliers”.

There are no official figures on the total number of people cherry-picking their vaccines. Still, dozens of towns in Brazil have sought to crack down on the practice, taking the names of those who refuse to be inoculated with the shot on offer, and moving them to the back of the line.

Public health experts in Brazil say the practice and the misinformation – or poorly understood information – that fuels it threaten to undermine the country’s vaccination campaign. It is also, they say, very selfish.

“The person is putting themselves at risk and ends up putting the entire system in danger,” said Alexandre Naime Barbosa, an infectious diseases professor at São Paulo State University. “It shows a lack of empathy, an enormous selfishness.”

“Choosing your vaccine is an ignorant gesture that lacks commitment to public health,” said Dimas Covas, the president of the Butantan Institute, which is producing CoronaVac in Brazil.

The trend comes as many countries have already vaccinated most of their populations and are lifting restrictions.

The Brazilian Society of Immunizations said most incidents involve people refusing vaccines from China’s Sinovac or – to a lesser extent – AstraZeneca. Instead, they seek out shots from Pfizer and Johnson & Johnson.

WhatsApp groups have popped up with people swapping tips on which vaccination centers offer the more sought-after shots.

Some are worried Sinovac’s CoronaVac does not work as well, while others fear Europe and the U.S. might not recognize it as travel restrictions are lifted for the fully vaccinated.

Brazilian health experts are rushing to dispel concerns, particularly about CoronaVac, fighting a wave of criticism, including from President Jair Bolsonaro, who said of the Chinese vaccine’s use earlier this month: “It didn’t work out.”

Late-stage trials in Brazil, before the vaccination campaign began, found CoronaVac to have a 50% efficacy at preventing symptomatic infection, compared to 76% for AstraZeneca and 95% for Pfizer. But in a real-world context, public health experts here argue, CoronaVac has shown itself to be very effective in reducing hospitalization and death.

“When you look at what really matters, reducing the number of hospitalizations and deaths, all the vaccines we have in Brazil have a very high efficacy,” Barbosa said.

In Serrana, a town in Sao Paulo state, where almost the entire adult population was vaccinated with CoronaVac as part of a study, deaths were reduced by 95%. Hospitalizations fell 86%, and symptomatic infections by 80%.

Public health experts have also stressed that the risk of developing blood clots resulting from taking the Astrazeneca vaccine is scarce. No vaccine, scientists stress, ever entirely removes the chance of death, but they are extremely rare.
