Various schools have mandated boosters for college students returning to campus this fall. There are some factors dad and mom, youngsters, and whoever is developing with insurance policies at schools might wish to think about. Since nobody has thought match to really generate any medical knowledge on boosters in school youngsters due to the continual state of COVID emergency we have now been in since early 2020, we’re left to attempt to extrapolate from an unlimited quantity of ecological knowledge and surrogate endpoints.
Whereas it might be unattainable to incorporate each single examine ever accomplished on the matter, there’s clearly sufficient knowledge to argue in opposition to their being the overwhelming scientific consensus that might be wanted to underpin a coverage that primarily forces people to obtain a medical therapeutic.
- Sturdy proof prior an infection / prior vaccination is protecting.The mandates don’t take prior vaccination or restoration from a previous an infection into consideration. It is a mistake. At this level, 97% of People have some protecting immunity from both vaccination or an infection. Latest knowledge in a post-Omicron an infection pattern, exhibits that these with prior an infection, with or with out related vaccination, have a sturdy rise in neutralizing antibodies after an Omicron an infection. Certainly, those that had been vaccinated alone with no prior an infection had modal titers just like those that had been unvaccinated. On this identical examine, 47% of the vaccinees had an mRNA vaccination inside the previous 3 months and 40% had been boosted. Moreover, these with a previous COVID an infection had proof of a rather more sturdy immune response within the respiratory tract in comparison with vaccinated people.
- Boosters don’t durably cease transmission or an infectionSadly, whereas there’s some knowledge that booster vaccinations minimize the chance of contracting Sars-cov2 variants by roughly half, this safety seems to quickly devolve over time as demonstrated by the numerous variant waves that closely boosted nations have demonstrated. A big CDC examine with knowledge from New York and California additionally discovered no additional profit in opposition to extreme illness from vaccination following an infection.A big Qatari examine famous BNT162b2 effectiveness was highest at 46.6% (95% CI: 33.4–57.2%) in opposition to symptomatic BA.1 and at 51.7% (95% CI: 43.2–58.9%) in opposition to symptomatic BA.2 infections within the first three months after the second dose, however declined to ~10% or beneath thereafter. Effectiveness rebounded to 59.9% (95% CI: 51.2–67.0%) and 43.7% (95% CI: 36.5–50.0%), respectively, within the first month after the booster dose, earlier than declining once more.
- Immunity following an infection is sturdyA wholesome immune system mounts an efficient response to SARS-CoV-2 an infection and this response persists over time. A latest July 2022 publication the place 96.7% of examine members had delicate or asymptomatic an infection exhibits that youngsters and younger adults mount a sturdy antibody response that can fade with time, however stays measurably current. As soon as once more this speaks to an anticipated sample of much less extreme illness with any subsequent an infection. This examine bolstered prior analysis that measured these responses as much as 12 months. The stimulation of an immune response after a light an infection may even be demonstrated within the absence of precise seroconversion (detectable prior an infection by antibodies) on the stage of T-cells. The presence of efficient immune reminiscence, each humoral (antibody) and mobile parts, after even a light SARS-CoV-2 an infection is now not a matter of debate. One is likely to be tempted to argue that repeated boosting can completely suppress an infection. Sadly, all out there proof means that this elevated safety from an infection is transient. A latest publication from Iceland has provided distinctive insights into what we will count on with post-Omicron reinfections in several vaccination classes. Whereas there have been vital issues with potential ascertainment bias and grouping of unvaccinated with 1 dose recipients, the authors discovered.Surprisingly, 2 or extra doses of vaccine had been related to a barely greater chance of reinfection in contrast with 1 dose or much less. This discovering must be interpreted with warning due to limitations of our examine, which embrace the shortcoming to regulate for the advanced relationships amongst prior an infection, vaccine eligibility, and underlying circumstances.A extra sturdy nationwide examine from Qatar, as soon as once more, supplies corroborating proof for the efficiency of prior an infection. Per the authors:No discernable variations in safety in opposition to symptomatic BA.1 and BA.2 an infection had been seen with earlier an infection, vaccination, and hybrid immunity. Vaccination enhanced safety amongst individuals who had had a earlier an infection. Hybrid immunity ensuing from earlier an infection and up to date booster vaccination conferred the strongest safety. [All provided excellent protection against severe outcomes.
- Boosting repeatedly against the original strain may have immunologic downsidesPer an NIH study, Omicron specific boosters did not elicit increases in Omicron specific neutralizing antibodies which is a concerning finding for a process called “imprinting”. This non-fringe opinion cited by vaccine expert Dr. Paul Offit in a New England Journal of Medicine editorial describes a process where the immune system gets locked into its first response to an infection, and is less able to respond to subsequent infections.
- Young college age men are a high-risk demographic for vaccine associated myocarditismRNA vaccine associated myocarditis/myopericarditis is an uncommon, but well-documented issue with COVID vaccines in young adults, particularly after 2nd or 3rd doses, and particularly in otherwise healthy males. There are issues related to the research on the relative frequencies of COVID/Vaccine myocarditis, but it does appear that younger men specifically may have a higher rate of vaccine myocarditis than COVID myocarditis.While the cases of vaccine myocarditis that do result in hospitalization largely appear to be self-limited and are associated with short hospital stays, long term follow up with cardiac MRIs demonstrates the persistence of scar in two-thirds of children who followed up. It is unknown at this time what the longer-term prognosis of this finding is.
Summary
- At this time, boosters do not durably protect individuals from infections, do not reduce transmission, expose individuals to the risk of vaccine associated myocarditis, and could even impair immunologic responses to future variants.
- Coercing patients to get a medical therapeutic in this context undermines trust in public health institutions and is unethical.

PS. Update at Western University.
PPS. I have to make the obligatory post-script here that I oversaw the administration of hundreds of mrna vaccines starting in March of 2021 in my cardiology clinic. The vaccine efficacy data for the original data was from thousands of patients and I certainly felt given the devastation wreaked on many of my patients in 2020 that the vaccines were the best chance of avoiding morbidity and mortality. The process to get the vaccines from the city department of health was a somewhat arduous 3-month process, and once the vaccines were on hand, there were daily reporting requirements that I dutifully performed for the many months we were administering vaccines. To accommodate the rush of patients, employees, volunteers, and conscripted children worked multiple weekends to administer the vaccines. So, I’m especially disgusted by medical colleagues and others who label any concerns registered about vaccine adverse events as “anti-vaxx”. Registering concern over a vaccine adverse event does not make doctors or patients “anti-vaxx”.
