Comments ‘no vaccine is 100% effective’, says state health measures could reduce risk
PORTLAND, Ore. (KTVZ) – The Oregon health authority said Thursday it has until April 2 identified 168 cases of COVID-19 vaccine breakthroughs – when vaccinated individuals are positive for the virus – by April 2, including three deaths.
OHA public health officials said it was a reminder that although the COFID-19 vaccines Pfizer, Moderna and Johnson & Johnson are all very effective in preventing serious COVID-19 diseases and deaths, no vaccine is 100% effective is not, and that there will be breakthroughs of vaccines.
These cases were reported in 25 provinces and in all health care regions (region 1:76; region 2:29; region 3:27; region 5: 9; region 6: 4; region 7:17; region 9: 6). OHA does not report the regions in which the deaths occurred.
Vaccine breakthrough cases are defined as cases in which an individual received a positive COVID-19 test result at least 14 days after the final dose of any COVID-19 vaccine series.
OHA cases can prevent breakthrough cases through basic public health interventions, such as masking, physical distance, and avoiding social gatherings.
The agency also noted: ‘The number of breakthrough cases in vaccines identified in Oregon represents a very small proportion of the more than 700,000 people in Oregon who have been completely vaccinated against COVID-19. Many of the cases identified by vaccines experienced asymptomatic infection and were tested for other reasons.
Eleven percent (n = 19) of vaccine breakthroughs were admitted to the hospital within 30 days of their positive test, and most occurred in people older than 65 or with underlying health conditions.
The three deaths accounted for less than 2% of vaccine breakthrough cases, and none of the vaccine breakthroughs were associated with a COVID-19 variant.
State and local epidemiologists continue to detect and investigate the breakthrough cases of vaccines and work closely with the Centers for Disease Control and Prevention to gather information that can provide insight into the characteristics associated with the breakthrough of vaccines. .
