Because of this, a medical professional who specializes in infectious diseases estimates that patients will need monthly booster injections of COVID-19 for the next four years in order to keep their immune systems on high alert in the event of a potentially fatal illness.

Dr. Jonathan Abraham, an assistant professor of microbiology and infectious disease specialist at Brigham and Women’s Hospital in Boston, says that COVID mutations and high transmission rates in some parts of the country mean that even people who have received a COVID vaccination are at risk for breakthrough infection.
Following the publication of a news release by Harvard University, Abraham said that vaccinations are still highly efficient in preventing major illness and death but that they are not 100 percent effective at preventing the virus’ acquisition and spread.
After taking all of this into account, he has come to a conclusion that owing to the high transmissibility of the mutations, they will need repeated boosters over the course of the next few years.
Because more virulent strains such as Delta will be fighting for space during this time period, Abraham believes that an updated COVID vaccine will be necessary during this era. According to Abraham, a genetic investigation undertaken by Abraham found that the original strain had “almost gone extinct” due to competition with more virulent strains such as Delta.
He discovered that the SARS-CoV-2 spike protein could evolve to the point where a booster with the updated strain antigen would be required to activate the immune system to detect the mutant virus over time. This is a possibility as a consequence of his research.
The finding is that this scenario is more consistent with what is done every year in terms of seasonal influenza virus vaccine and is also less damaging than the other scenarios.
As soon as antibody levels begin to decline after the initial vaccination, according to Abraham, a clinical immunologist in the United Kingdom, booster doses are delivered to give the immune system a little push in the correct direction.
According to him, it worked by tricking the immune system into thinking it was faced with a sickness once again, forcing antibody-producing lymphocytes and other immune cells to be summoned from storage and put into high gear once more. It is feasible to increase both the quantity and the quality of antibodies produced in the body by using a range of different techniques.
Furthermore, according to Abraham, immunostimulants aid in the learning of the immune system and the generation of antibodies that are more particularly targeted against the germs that are causing illness.
Certain immunizations, such as tetanus, diphtheria, and pertussis (Tdap) vaccine, need the administration of booster doses, whilst others, such as the influenza vaccine, are not required. This is owing to the fact that immunity is waning.
Pre-existing and primed immune responses, such as those evidenced by measurable antibody levels, are necessary for efficient disease prevention and therapy under specific circumstances. According to Abraham, an adjuvant is required to restore immune function to normal levels over time since antibody levels diminish over time with exposure to the environment.
