Israeli experts continue seeing post-Covid symptoms that affect quality of life even in young, healthy patients.

Israeli study determines that a third dose five months after the initial two Pfizer doses reduces risk of death from the disease dramatically.

Study is first to estimate effectiveness of a third dose of an mRNA Covid-19 vaccine against severe outcomes and within subgroups.

Israeli study also shows 93% effectiveness in preventing the spread of symptomatic infection within seven to 21 days of the second Pfizer dose.

Study of 800,000 Covid test takers, half inoculated with the first dose and half not, shows no difference in infection rate until two weeks later.
