Orders of magnitude

At the beginning of April, the MHRA published an analysis of vaccine safety reports in the UK and concluded that despite now finding increased evidence of rare blood clots following administration of AZD1222 from AstraZeneca (consistent with previous reports from Europe) the benefits of vaccination still outweigh the risks.

Resetting certificates

Web site certification supports the key exchange enabling secure encrypted communication between browser clients and server applications. This is why industry giant Google launched a campaign in 2014 that all web applications should use a browser-recognised certificate authority (CA) and offer encrypted access.
