Антитела или Т-клетки: какой тип иммунитета лучше

Почему в отдельных случаях люди, переболевшие COVID-19, заболевают повторно? Можно ли что-то сделать с этой проблемой? Ученые из Швеции решили  найти ответы на эти непростые вопросы.

Их исследования показали, что после инфицирования клеточный иммунитет обладает гораздо более серьезными возможностями, чем тот, что дают антитела. В этом убедились специалисты, когда взяли образцы крови 200 пациентов, которые перенесли коронавирус в легкой или бессимптомной форме. Т-клетки, которые изначально запускают иммунный ответ на выработку антител, были обнаружены у трети пациентов. Люди с таким иммунитетом при повторном заражении будут болеть бессимптомно или с легкими проявлениями.

При этом наличие антител не гарантирует 100-процентную защиту от вируса. Ученые именно поэтому настаивают на том, что пациентам, которые уже перенесли заболевание стоит делать вакцину.
