According to a report, international studies confirm that mRNA vaccines such as Pfizer and Moderna are substantially more effective than traditional vaccines such as Astrazenica and Johnson and Johnson/Janssen against delta and previous strains of covid 19.
According to the report scientific evidence proves that boosting a single Astrazenica shot with Pfizer or Moderna induces around ten times the antibodies than two shots of Astrazenica could.
Reportedly .4% of those tested for covid 19 in Ireland over the past fortnight were positive, amounting to 20,000 cases of which 17% were fully vaccinated.
