Good news from UK health authorities: Pfizer/BioNTech and AstraZeneca’s corona vaccines prove very effective against hospitalization (and possibly serious illness) from the delta variant, also known as the Indian variant of the coronavirus.

 

New research from Public Health England (PHE) shows that Pfizer provides 96 percent protection against hospitalization after two doses and AstraZeneca 92 percent. That is comparable to the effectiveness against hospitalization by the alpha variant or the British variant of the virus.

Further research is needed to determine the extent to which vaccines protect against death from the delta variant. But it is expected that this will also be very good.

The study involved more than 14,000 patients with the delta variant between 12 April and 4 June. 166 had to be hospitalized. According to previous research by PHE, one dose was 17 percent less effective in preventing the symptomatic disease from the delta variant than the alpha variant.

According to British Health Secretary Matt Hancock, the study proves the importance of full vaccination. Flemish Minister of Health Wouter Beke (CD&V) is also delighted with the results. “Good news! Research from the UK indicates that the vaccines that should protect us against COVID-19 are also very effective against the Delta variant. The more vaccinated, the better we protect ourselves and each other.”

In the United Kingdom, the delta variant is now the dominant one. In Belgium, according to the most recent bulletin of the health institute Sciensano, he is only good for 3.9 percent of all infections, but that number seems to be increasing. Experts fear that he could also become dominant with us.
