The Pfizer vaccine is highly effective in preventing COVID-19 infections, deaths, and hospitalizations, according to a new study in Spain.
The investigation followed more than 116,000 nursing home residents, staff, and healthcare workers who were vaccinated in Catalonia starting late last December.
Not only did the study confirm the results of Pfizer’s clinical trial in terms of the vaccine’s ability to prevent severe COVID-19 and deaths, but it also found that the vaccine was “highly effective” in protecting against infections in nursing homes.
The study was recently published as a preprint in the Lancet medical journal and is affiliated with the Catalan Health Department, the Catalan Institute of Health, the University of Oxford, and the Autonomous University of Barcelona.
Researchers found that after two doses, total coronavirus infections – symptomatic and asymptomatic – dropped by 88% in nursing home residents, 92% in nursing home staff, and 95% in healthcare workers.
After the first dose, contagions dropped by a more modest 35% to 42% across all groups.
In light of the evidence, the study recommends that people must protect themselves from the virus between vaccine doses, particularly in the first two weeks after the initial jab.
After two doses, the study also found a “striking” 97% and 98% reduction in COVID-19 hospitalizations and deaths.
Researchers in Israel and Scotland have carried out similar real-life studies on vaccines, but this is the first focusing on nursing homes in Spain.
