Around 0.01 per cent of people grew infected with COVID between January and April despite being fully vaccinated.
A study by the US government affirmed the shots’ high potency on Tuesday. The report was published by the Centres for Disease Control and Prevention (CDC). It documented the so-called breakthrough cases among 101 million fully inoculated people in the United States.
Even though FDA approved vaccines are highly effective, breakthrough cases are expected. Especially before population immunity reaches ample levels to decrease transmission further, the report said. The report studied the period from the 1st of January to the 30th of April.
A total of 10,262 infections were documented at 14 days or more after the final dose of vaccine finally approved by the food and drug administration Pfizer, Johnson & Johnson, and Moderna. Of these cases, 6,446 or 63 per cent occurred in females, and the medial patients’ age was 58 years.
Among the total number of breakthrough infections are 2,725 or 27 per cent were asymptomatic. 706 or 7 per cent were hospitalized for COVID related issues, and 132 or 1 per cent died from COVID related reasons.
The rate of breakthrough infections is thus roughly 0.01 per cent. Moreover, the hospitalization per cent is 0.0007, and the total death tolls are around 0.0001 per cent.
The genomic sequences are available for five per cent of all infections. Moreover, it showed that 64 per cent of cases came from variants of concerns. The most significant was B.1.1.7 that was first identified in the United Kingdom.
When did this study take place?
The study occurred during a period when the COVID was surging through the United States. With approximately 3,55000 cases reported in the last week of April alone. The authors said that the number of COVID cases among vaccinated people would far exceed the number of breakthrough cases.
The author noted that the actual number of breakthrough cases are likely to be substantially higher. Because most will result in asymptomatic and mild infections that won’t be tested. The lack of widespread surveillance systems also limits the data on variants.
About 164 million people, 50% of the total US population, have now had at least one dose of vaccine, while 39% are fully vaccinated.
