Yorkshire currently has the highest coronavirus infection rate in the country, partly down to an outbreak at the Clipper factory in Selby.The steep drop in patients is fresh evidence of the combined impact of the lockdown and vaccines in helping reduce the number of Covid-19 infections that lead to hospital admission.
Recent research by the Office for National Statistics and Oxford University found that Covid-19 infections “fell significantly” by 65 per cent after a first dose of the Oxford/AstraZeneca or Pfizer/BioNTech vaccines, while two doses of the Pfizer/BioNTech vaccine offered similar levels of protection as a previous Covid-19 infection.
Vaccination was also found to be just as effective in individuals over 75 years or with underlying health conditions, as it was in those under 75 years or without underlying conditions.
Meanwhile hospital admissions of patients with Covid-19 are back to levels last seen in early September.
A total of 76 admissions were reported for May 4. This is down 98 per cent from the peak on January 12.
