In the early days of the COVID-19 pandemic, pulmonologist Joseph Varon offered an opinion that made headlines around the world and went viral on social media. Varon was fighting two wars, he said: one against COVID and one against stupidity.

A fourth dose of the COVID-19 vaccine from Pfizer and BioNTech provided significant added protection against severe disease, hospitalization and death for at least a month in older individuals, according to a study from Israel conducted when the Omicron variant was dominant.

A new study shows the persistent syndrome of Covid-19 after-effects known as long Covid can develop after “breakthrough” infections in vaccinated people. Other new findings suggest a gene that helps the coronavirus reproduce itself might contribute to life-threatening Covid-19 in young, otherwise healthy people.

Evidence is emerging that not only can Covid-19 vaccines help prevent long Covid, but they could serve as a form of “rescue” for those already stricken with the condition.
