Will ‘Forever Boosting’ be effective in combating the Coronavirus?

Until a year ago, it was believed that just two doses of a Covid-19 vaccine — or even one, in the case of Johnson & Johnson’s version — would be adequate to provide protection against the coronavirus infection.

Due of the very infectious Omicron strain, Israel has started providing fourth doses to select high-risk populations in response to the outbreak. The Centers for Disease Control and Prevention (CDC) said on Wednesday that teenagers are now eligible for booster injections and that they would no longer refer to anybody as “completely vaccinated” since two doses are no longer considered sufficient.

Instead, one’s vaccination status will now be determined based on whether or not they are “up to date.” It should come as no surprise that many Americans are wondering where this is all going to end. Are we expected to roll up our sleeves every few months to get booster shots?

Scientists have been repeatedly humbled by a virus that has defied predictions, and they are wary to forecast what will happen in the future. However, in interviews this week, over a dozen people said that, no matter what occurs, aiming to increase the total population every few months is not feasible. It also doesn’t make a lot of logical scientific sense.

According to Akiko Iwasaki, an immunologist at Yale University, “it’s not uncommon to provide immunizations on a regular basis, but I believe there are better alternatives than administering boosters every six months.” There are other techniques that might “get us out of this forever-boosting type of a scenario,” she said.

Starting with the obvious, getting individuals to stand in line for injections every few months is almost certainly a lost proposition. Approximately 73 percent of individuals in the United States are completely vaccinated, but just slightly more than a third have chosen to get a booster shot.

Booster injections unquestionably raise antibody levels and aid in the prevention of infection — and, as a consequence, they may alleviate strain on the health-care system by temporarily delaying the spread of the virus, which would otherwise be catastrophic. All of the specialists agreed that, in light of the recent Omicron outbreak, Americans should get a third dosage as soon as feasible.

However, the immunity boost is very temporary; early tests have already shown a drop in antibody levels only a few weeks after receiving a third treatment. Even when antibody levels are at their highest, the increase may not always prevent infection with Omicron, which is less susceptible to the body’s immune defences than other bacteria.

In addition to the existing immunizations, nasal or oral vaccine boosters might be used in conjunction with them. These vaccines are more effective at preventing infection because they cover the nose and other mucosal surfaces — which serve as entrance routes for the virus.

Many medical professionals were originally opposed to the concept of administering a booster injection at all. The early vaccination regimens, according to some, were sufficient to keep the vast majority of individuals out of the hospital, and that this should be the actual measure of a vaccine’s effectiveness.

Some scientists believe that, in order to restrict the spread of the virus, techniques other than vaccinations would be more beneficial to Americans than vaccines. Pneumococcus vaccination, for example, provides indirect protection to older persons by decreasing the spread of the disease among young children.

Sarah Cobey, an evolutionary biologist at the University of Chicago, believes that increasing the amount of ventilation in schools will help to reduce the transmission of the coronavirus among children and their contacts.

Experts say that before the United States can embrace any policy, whether it is periodic boosters or other techniques, the Biden administration must first clarify what it is attempting to achieve.
