If your daughter had a Covid variant when she was 3 1/2 and had it bad then she probably has all the immunity she needs for the current strains - we know from SARS, MERS, Covid 19 etc that the strains get weaker after each iteration but the WHO and other NWO type organisations prefer to push their vaccine narrative and are only too eager to put the planet in lockdown at first opportunity… or maybe people haven’t learnt🤔
