Pfizer’s vax drastically reduces COVID-19 infections—study


According to a new study in Spain, the Pfizer vaccine has shown promising effects in preventing Covid-19 infections, as well as reducing severe cases and deaths.

The study followed over 116,000 nursing home residents, staffs, and healthcare workers who were vaccinated in Catalonia starting last December.

Aside from confirming Pfizer’s clinical trial results in terms of the vaccine’s ability to prevent hospitalizations and deaths, the study has 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 percent in nursing home residents, 92 percent in nursing home staff, and 95 percent in healthcare workers.

After the first dose, transmissions dropped by a more modest 35 percent to 42 percent across all groups.

However, the study has recommended that people protect themselves from the virus between vaccine doses, particularly in the first two weeks after the initial jab.

After two doses, the study further saw a “striking” 97 percent and 98 percent 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.

According to the report, nursing home residents are “extremely vulnerable to severe and lethal forms of Covid-19” and have been “under-represented in previous studies.”

The researchers said they will continue following up on the participants to keep track of the long-term effects of vaccines.

They also acknowledged that around 15 percent to 20 percent of the drop in infections could be attributed to other factors, such as community contagion rates or extra protective measures.

Nevertheless, the researchers stressed that the findings should “reassure the population of the major benefits associated with the ongoing vaccination campaign in Spain and elsewhere.”
