There's been a mini-surge of new clinical trials for next generation Covid vax:
- an intranasal vaccine from the NIAID going into phase 1;
- another intranasal vaccine got a US Project NextGen-funded big phase 2 trial - & so did an encouraging nextgen vax for people with immunosuppression;
- another vax designed to improve protection for people with immunosuppression is in phase 1 in Australia.
All this & more in my new update post @PLOS
