Pfizer vaccine reduces coronovirus infection among entire population, Israeli data

Israeli research suggests that Pfizer-produced coronavirus vaccines not only protect people from infecting COVID-19, but also help immunity prevent people from spreading the disease to others.

The question of whether the vaccine would help prevent those who still had it from being carriers was an important issue as inoculation was rolled out worldwide.

Clinical research conducted by Israel’s largest health fund Clatit showed a significant decline in infections among 200,000 people over 60 years of age and two weeks after the first vaccination was given. Not all of the 200,000 people involved in the research received vaccination.

Prof. Head of innovation at Clannit. Ran Balisar states that no effect is seen on normal infection rates from 5 to 12 days after the first dose of two-stage vaccination.

According to the data, there was a slight decline in morbidity on the 13th, but there was a 33% drop in the prevalence of the disease between vaccinators and those not vaccinated for 14 days.

On December 20, 2020, Israel began vaccinating its population using the Pfizer vaccine. So far, the country has given the first shots to around two million people and has already started administering the second dose.

This is the first evidence that the Pfizer vaccine not only prevents a person from contracting COVID-19 after exposure to a coronovirus, but it also prevents that exposed person from transmitting the virus to others.

It is not yet clear whether the dose of the first vaccine reduces morbidity by 33%, or what the percentage will be after the second dose, but Israeli health experts believe the data shows a significant drop in the spread of the virus is.

Pro. Balischer said that while the results are only preliminary, they are “very encouraging.”

“It is important to note that these results do not show that there is complete protection from the disease,” he said.

“Therefore, those who have been vaccinated should still be vigilant, wear face masks and obey public health orders” to protect those around them.

Balisar said experts are hoping to prove in the coming weeks that the vaccine also helps reduce COVID for infected people and severe cases of hospitalization.
