In public health, a “breakthrough case” is when a fully vaccinated person later gets the disease they were vaccinated for. No vaccine provides 100 percent protection against infection, so breakthrough cases are not new, and not unique, to COVID-19. There have been reports of COVID-19 breakthrough cases in South Carolina and throughout the U.S., and this is not unexpected.
COVID-19 vaccines are very effective in preventing mild symptoms, severe disease, and hospitalizations due to COVID-19 disease. But it is still possible for a fully vaccinated person to get infected if they are exposed to the virus. These individuals may have no symptoms or mild symptoms, yet they can still spread the virus to others. That’s why even after getting vaccinated for COVID-19 we recommend continuing to wear a mask, keep your distance, avoid crowded settings, and wash your hands: this helps you to prevent exposure to the virus and unknowingly spreading it to others.
Because fully vaccinated people usually have some immunity against the disease, breakthrough cases usually have either no symptoms or mild symptoms. A breakthrough case occurs when an individual has had a lower immune response from the vaccine. No vaccine is 100 percent effective.
The Centers for Disease Control (CDC) is currently investigating all reports of COVID-19 breakthrough cases. Breakthrough cases are studied as part of the CDC’s ongoing research to assess how COVID-19 vaccines work in real-world conditions. According to the CDC, assessing how vaccines work in the real world is important to:
People with breakthrough COVID-19 infections still need to follow all of the recommended quarantine procedures.
Because the vaccines require about two weeks to become effective, a person is not considered fully vaccinated until two weeks after they completed the recommended number of doses for the vaccine they received. A person who tests positive for COVID-19 between their first and second doses of two-dose vaccines, or a person who test positive before the two-week period after their final dose, is not considered a breakthrough case.
DHEC continues to work closely with the CDC during these ongoing national and international efforts to accurately identify breakthrough cases. DHEC will continue to keep South Carolinians updated and informed and new information will be provided as it becomes available.

OLYMPIA -- The Washington State Department of Health (DOH) is investigating reports of people in the state who tested positive for COVID-19 more than two weeks after being fully vaccinated. Scientists call these “vaccine breakthrough” cases, which are expected with any vaccine.
Large-scale clinical studies found that COVID-19 vaccines reduced the risk of getting COVID-19 in vaccinated people by up to 95% compared to people that did not receive the vaccine. However, the vaccines are not 100% effective in preventing infection. This means a small percentage of fully vaccinated people can be expected to still get COVID-19. These are identified as breakthrough cases.
Out of one million fully vaccinated individuals in Washington state, epidemiologists report evidence of 102 breakthrough cases since February 1, 2021, which represents .01 percent of vaccinated people in Washington. Breakthrough cases have been identified in 18 counties. The majority of those in Washington state with confirmed vaccine breakthrough experienced only mild symptoms, if any. However, since February 1, eight people with vaccine breakthrough have been hospitalized. DOH is investigating two potential vaccine breakthrough cases where the patients died. Both patients were more than 80 years old and suffered underlying health issues. Further investigation will help to identify patterns among people who have COVID-19 after vaccination, such as if a virus variant may have caused the infection.
"It is important to remember that every vaccine on the market right now prevents severe disease and death in most cases," said Umair A. Shah, MD, MPH, Secretary of Health. "People should still get vaccinated as soon as they are eligible, and encourage friends, loved ones, and co-workers to do the same."
DOH confirms a breakthrough case with a positive PCR test or Antigen test in a person more than two weeks after he or she has received their final dose of the COVID-19 vaccine. Additional investigations help determine clinical and outbreak information.
"Finding evidence of vaccine breakthrough cases reminds us that, even if you have been vaccinated, you still need to wear a mask, practice socially distancing, and wash your hands to prevent spreading COVID-19 to others who have not been vaccinated," said Secretary Shah.
The Department of Health will provide a regular report regarding vaccine breakthrough in Washington state beginning in late April.

I think we can not relax until herd immunity is formed and the virus dies out
from the community.

We should keep our face masks and social distancing until the very end of the pandemic.
Don't be like the stupid immature Trump and his Republicans.
My and our own lives depend on it.
Do you know that our lives are much more precious than the spoiled whites' lives.
We should be holding on to it tighter than the whites do.

As fully vaccinated people start to get together socially,
there appears to be confusion and a significant unknown in regard to
what to do wth mask, social distancing, etc, especially in the possibility
of the breakthrough infection which may well turn out to be a mild case.
It seems to me that unfortunately each of us winds up having no choice
but making a judgement call depending upon the circumstances we are in.
