Within the fifth century B.C., Hippocrates first reported a illness with “flu-like signs” spreading throughout northern Greece. Years later, in Renaissance Florence, round A.D. 1300 a flu virus known as “influenza di freddo” hit the Italian metropolis with a vengeance. Historical past reveals that we’ve been coping with the flu for hundreds of years, whereas COVID-19 is a comparably new contagion. Nonetheless, in accordance with consultants, the flu has offered the groundwork for a way we would reply to COVID-19 sooner or later.
Rajeev Fernando, an infectious illness skilled and fellow at Harvard Medical College, says that we’re in a really completely different place than we had been with the virus in 2020 as a result of now round 90 % of People have been contaminated with COVID-19. Many people have “hybrid immunity,” that means we’ve been vaccinated towards the an infection and contracted it. Consequently, we’re much less prone to want vaccines each 4 months as we did a couple of years in the past.
An Annual Booster?
Whereas there’s rather a lot we don’t know, Fernando contends that we could possibly function equally as we do round influenza, taking a look at the kind of flu pressure that’s circulating within the southern hemisphere and altering every year’s vaccine accordingly. “It’s affordable to assume this may work with the COVID-19 vaccine as properly and {that a} yearly vaccine could possibly be advisable, however the distinction is that we’ve years of flu information that we simply don’t but have with COVID-19,” says Fernando.
As new variants come out, says Fernando, we’ve to have the ability to modify accordingly and suggest an up to date vaccine when there’s a menace. Many vaccine producers have already stated that they may be capable to come out with a brand new vaccine inside 100 days if a harmful variant rears its head. In that case, a vaccine is perhaps wanted greater than as soon as per 12 months.

Just like the flu vaccine, the best suggestion for a COVID-19 vaccine can be aged and immunocompromised sufferers. Nonetheless, those that should not immunocompromised also can select to get one. However as the information unfolds, we’ll have a greater concept of who must get an annual jab. “Both manner, we ought to be ready that if somebody who is just not immunocompromised needs to get the vaccine, they shouldn’t be turned away,” says Fernando. Moreover, he’s involved that as President Biden lifts the COVID Emergency Declaration, COVID-19 vaccines will not be free to those that want them essentially the most.
The Threat of Lengthy COVID
However consultants aren’t in full settlement on what the way forward for vaccines will appear to be. Grace McComsey, MD, who leads the Lengthy COVID RECOVER examine at University Hospitals Health System in Cleveland, agrees that we might have a couple of shot per 12 months, primarily based on variants. However for her, the bigger concern round COVID-19 is lengthy COVID.

Whereas most individuals are much less probably at this level to die from acute COVID-19, lengthy COVID impacts a large swath of sufferers from all walks of life, she says. There are such a lot of extra issues in those that survive COVID-19 in comparison with the flu, and we’re seeing so many new well being circumstances like mind fog, lethargy, blood clots, gastrointestinal points and so many others which are arising on account of this illness. “For my part, stopping lengthy COVID ought to be the principle concern and the rationale why everybody must get an annual immunization if not a couple of,” says McComsey.
There’s nonetheless rather a lot we don’t learn about how COVID-19 will impression us sooner or later as extra variants come out and we’ve a greater understanding of lengthy COVID. All of this can have an effect on who must get an annual shot. However what is obvious is that COVID-19 isn’t over, and our response to it shouldn’t be both. And in contrast to the flu, for those who survive COVID-19, it doesn’t imply you’re within the clear.
