I would say that if any major problem with ade were to occur it would be before summer or maybe later when cases start rising again by autumn and winter.
New variants might be tricky...
What concerns me the most is that this are not exactly "vaccines"
"A recent study showed that viral shedding in the upper respiratory tract was indistinguishable between patients with asymptomatic and symptomatic COVID-19"
search for "Clinical and immunological assessment of asymptomatic SARS-CoV-2 infections"
If the virus circulates between vaccinated and vaccinated, mutations will occur that evade the vaccine effectiveness, potentially being way more deadly to unvaccinated people. aka "Leaky vaccine" aka "Negroid Democide" aka "Mass Depopulation" aka "Permanent Lockdowns"
If this doesn't happen, new variants are inevitable, we might get it under control in the modern world but you better get used to this, it's not going to get as before 2020 in this or the next 3 years, at least.
Mass testing will be a thing, working from home will never ever go away, online shopping will continue to grow, you will still use a mask indoors, lockdowns from time to time...
And get ready for the BOOSTER SHOT
And vaccines for new variants will not require so much testing, they will just say that it's a minor alteration and doesn't affect safety.
