Glad to hear that , antobody tests are needed for everyone before taking any vaccine , if then the child or adult has antibodies against covid then there is no need to take the vaccine as that person is immune already it has been proven in America tests that natural immunity is stronger than the vaccine , I have myself got antibodies against covid having had covid in July 21 and so I won't get vaccinated as I don't need it , I also had an antigen test and I don't have covid now , if varients infect me in future my antibodies will change to beat the varients so I'm not worried about any varients neither in future , also the vaccine only lasts for 6 months antibodies last forever
