How long do antibodies last in children

[HairyToity]

My primary age children had covid at Christmas. They've been in contact with covid again. Could someone point me in the direction of any medical journals with details on how long childrens antibodies last? I'm just wondering if they will get it again. DH and I are both double vaccinated.

There's essentially no reliable evidence on this.

There is strong evidence that none of you are at any significant risk even if you do catch covid.

Interesting question but I am sure sure there is much evidence on this. In adults most of the evidence points to 6 months plus for natural infection. Fewer antibodies are produced in milder cases so I would assume a shorter time than for adults.

The research on antibodies to the cold virus is interesting with some evidence that in children common cold antibodies help to neutralise covid antibodies.

There's no definitive answer to this. Antibodies to SARS Cov-1 have been found 17 years later in people who caught it. Will SARS Cov-2 be similar?

Then there's the question of whether antibodies are the important thing, or whether there are other mechanisms providing a level of immunity even if antibodies are low or absent.

Hmmm. I was hoping it'd be like chicken pox, and you catch it in childhood, it's mild and you have long-lasting immunity.

It's almost certainly more like other "common cold" viruses, where catching it in childhood does give you long lasting protection from serious harm, but does not prevent you from catching it again with mild symptoms.

Indeed in children it appears to be milder than other "common cold" viruses such as RSV which is certainly hospitalising more kids than covid at the moment.
