It was found that most people who were vaccinated with the ancestral strain of Covid-19 (Wuhan strain) were protected against the Delta variant but not against the Omicron variant. PBMCs (peripheral blood mononuclear cells) and serum were obtained from five successfully vaccinated individuals with good neutralizing antibody titres and cytotoxic (CTL) activity against the Wuhan straininfected targets. Pooled serum was transferred into unrelated recipient "A" and pooled purified T cells were transferred into unrelated recipient "B". Which one of the following is likely to be observed?
1
"A" will be protected against both the ancestral strain and the Delta variant.
2
"B" will be protected against ancestral strain but not against the Delta variant.
3
"A" will be protected against infection with the Omicron variant.
4
"A" will make antibodies against interferon gamma present in the donor serum.
