If you’ve been completely immunized against COVID-19, you may believe you’re no longer at risk of acquiring the coronavirus. However, reports of fully vaccinated individuals testing positive for COVID-19 are increasing in tandem with the rising number of new COVID-19 cases worldwide and increased worry about highly transmissible strains like the delta variant.
Members of the New York Yankees, Olympic gymnast Kara Eaker of the United States, and UK health minister Sajid Javid are among individuals who have been diagnosed with a “breakthrough virus.”
As terrifying as the phrase may seem, the current COVID-19 vaccinations are still highly effective at avoiding symptomatic infections, and breakthrough infections are very uncommon. But how widespread and harmful are they? Here’s a rundown of everything you need to know.
1. What Is a ‘Breakthrough Infection,’ and What Does It Mean?
There is no such thing as a 100% effective vaccination. The polio vaccination developed by Dr. Jonas Salk was 80-90 percent successful in avoiding paralysis. During major outbreaks, even the gold standard measles vaccine had a 94 percent effectiveness rate among a well vaccinated population.
Clinical studies showed that Pfizer and Moderna’s mRNA vaccines were 94 percent–95 percent effective for avoiding symptomatic COVID-19, which was considerably better than expected.
A brief reminder: A vaccination effectiveness of 95% does not imply that the injection will protect 95% of individuals while the other 5% will get infected with the virus. Vaccine effectiveness is a measure of relative risk in which a group of vaccinated individuals is compared to a group of unvaccinated people under the same exposure circumstances. Consider a three-month trial in which 100 uninfected individuals out of 10,000 were infected with COVID-19. Five individuals who have been vaccinated should become ill at the same time. It was 5% of the 100 unvaccinated individuals who were sick, not 5% of the whole group of 10,000.
Scientists refer to infections that occur after vaccination as “breakthrough” infections because the virus has broken through the vaccine’s protective barrier.
2. How Common Is COVID-19 Infection Among Vaccinated People?
Breakthrough infections are occurring at a higher rate than previously thought, and the delta variant’s dominance is likely to increase. Infections among vaccinated individuals, on the other hand, are still uncommon and typically produce little or no symptoms.
Between January 1 and April 30, 2021, 46 US states and territories voluntarily reported 10,262 breakthrough infections to the US Centers for Disease Control and Prevention. During the same time period, there were 11.8 million COVID-19 diagnoses in total.
Vaccine breakthrough cases were no longer monitored by the CDC after May 1, 2021, unless they resulted in hospitalization or death. Out of more than 159 million individuals completely vaccinated in the United States, 5,914 patients with COVID-19 vaccine breakthrough infections were hospitalized or died until July 19, 2021.
Between December 15, 2020, and March 31, 2021, 410 veterans who received two doses of the Pfizer or Moderna vaccine had breakthrough infections, accounting for 0.16 percent of the total. Similarly, a research in New York found 86 instances of COVID-19 breakthrough infections among 126,367 individuals who were completely vaccinated, mainly with mRNA vaccines, between February 1 and April 30, 2021. This represents 0.07 percent of the completely vaccinated population and 1.2 percent of all COVID-19 cases.
3. Is a COVID-19 Breakthrough Infection Serious?
A vaccination breakthrough infection, according to the CDC, occurs when a nasal swab detects SARS-CoV-2 RNA or protein more than 14 days after a person has received all of the required doses of an FDA-approved COVID-19 vaccine.
It’s important to note that a breakthrough infection doesn’t always imply the individual is ill; in fact, the CDC found that 27% of breakthrough infections were asymptomatic. Only 10% of the individuals who were infected at the time of the breakthrough were hospitalized (some for causes other than COVID-19), and only 2% died. In contrast, nearly 6% of reported illnesses were deadly in the spring of 2020, when vaccinations were not yet available.
None of the breakthrough infections in a study at U.S. military medical centers resulted in hospitalization. In another research, vaccinated individuals who tested positive for COVID-19 after only one dose of Pfizer vaccine had a quarter less virus in their systems than those who were unprotected and tested positive.
4. What Factors Increase the Chances of a Breakthrough Infection?
More than 5% of COVID-19 tests are positive on average throughout the country; in Alabama, Mississippi, and Oklahoma, the positivity rate is above 30%. When there is a lot of coronavirus circulating in a population, the chances of a breakthrough infection increase.
Close contact settings, such as a crowded workplace, a party, a restaurant, or a stadium, increase the risk. In addition, health care workers who have frequent contact with infected patients are more likely to contract a new infection.
Women account for 63 percent of breakthrough infections, according to CDC statistics from throughout the country for unknown reasons. Women were also shown to be the majority of breakthrough instances in several smaller investigations.
Vaccines cause a less strong immune response in the elderly, and the risk of a breakthrough infection increases with age. Patients aged 65 and older accounted for 75 percent of the breakthrough cases monitored by the CDC.
Immunocompromised individuals and those with underlying illnesses such as high blood pressure, diabetes, heart disease, chronic renal and lung disease, and cancer are more likely to develop breakthrough infections, which may result in severe COVID-19. In one research, completely vaccinated organ transplant patients were 82 times more likely to have a breakthrough infection than the vaccinated general population, with a 485-fold greater risk of hospitalization and death following a breakthrough infection.
5. What Effects Do Variants Like Delta Have?
Earlier strains of the SARS-CoV-2 virus were used to create today’s vaccines. Since then, additional variations have evolved, many of which are more effective at evading the antibodies generated by presently approved vaccinations. Existing vaccinations are still highly successful at avoiding hospitalization against these variations, although they are less effective than they were against earlier versions.
According to Public Health England, two doses of the mRNA vaccines were only 79 percent successful in preventing symptomatic illness with delta, compared to 89 percent effective with the earlier alpha version. Only 35% of people were protected against delta with a single dosage.
Fully vaccinated individuals made up around 12.5 percent of the 229,218 delta variant infections reported in England until July 19.
With high immunization rates, Israel has revealed that complete vaccination with the Pfizer vaccine may only be 39 percent to 40.5 percent effective in preventing delta variant infections of any severity, compared to early predictions of 90 percent. According to Israel’s results, the effectiveness of COVID-19 vaccinations in avoiding infection and symptomatic illness decreases after six months. The good news is that the vaccination is still quite effective at preventing hospitalization (88%) and severe illness (91.4%) caused by the now-dominant delta form.
6. So, How Effective Are Vaccines?
By the end of July 2021, 49.1% of the US population, or slightly over 163 million individuals, had received all of their vaccines. Vaccines have been administered to almost 90 percent of Americans over the age of 65.
According to scientists’ calculations, immunization may have saved about 279,000 lives and avoided up to 1.25 million hospitalizations in the United States by the end of June 2021. COVID-19 vaccinations may have saved approximately 30,300 deaths, 46,300 hospitalizations, and 8.15 million infections in England. From the height of the pandemic in Israel, the high vaccination rate is believed to have resulted in a 77 percent decrease in cases and a 68 percent drop in hospitalizations.
Only 150 of the more than 18,000 individuals who died in May as a result of COVID-19 in the United States were completely vaccinated. As a result, virtually all COVID-19 fatalities in the United States occur among the unvaccinated.
As Anthony Fauci phrased it, the United States is becoming “nearly like two Americas,” split between the vaccinated and the unvaccinated. Those who have not been completely vaccinated against COVID-19 are still at danger of contracting the coronavirus, which has killed over 600,000 people in the United States so far.
