If a report published today by the Health Information and Quality Authority (HQIA) in the Republic of Ireland is correct even IF a vaccine is administered to everyone further evidence shows that its still unclear if long-term immunity to Covid 19 is even possible as it suggests that it may be possible to get reinfected again. The Report also dismissed the possible use of mass screening at airports using devices such as infrared thermal scanners as these were not found to be effective in identifying infectious individuals or in limiting the spread of coronavirus. All of which if accurate would I'm sure stop a lot of Countries rushing to reopen their borders quickly again too.
