Why the UK can’t rely on boosters to get through each new wave of Covid | Danny Altmann
The evidence suggests performance could be less predictable and effective in the future – though there are promising developments

Most hardly dared imagine that effective vaccines might appear in a fraction of the time taken for previous efforts, effectively stemming the pandemic tide.
But despite the success of the vaccines in greatly reducing the odds of hospitalisation or death, viral evolution had plenty more to throw at us. The onslaught of highly immune-evasive variants was, for most of us in immunology and virology, unforeseen. We’d come to think of the coronavirus family as being rather more stable – less error-prone in terms of mutations – than many viruses. And we had never before had to roll out relatively new ways of developing vaccines, involving mRNA or recombinant adenoviruses, at this scale and in the heat of battle.
