The Delta Variant: Concerns about its Impact on Vaccinated Individuals
TLDR The Delta variant, responsible for 93% of new COVID-19 cases in the US, has raised concerns about vaccinated individuals spreading the virus. While vaccinated individuals can still transmit the Delta variant, they are less likely to get seriously ill compared to the unvaccinated.
Timestamped Summary
00:00
The Delta variant is responsible for 93% of new COVID-19 cases in the US and there are concerns about its impact on vaccinated individuals.
03:27
The CDC has found that there may be no difference in viral load between vaccinated and unvaccinated individuals infected with the Delta variant, which has raised concerns about the potential for vaccinated individuals to spread the virus.
06:52
Vaccinated individuals can have the same amount of virus in their noses as unvaccinated individuals, suggesting that vaccinated people can spread the Delta variant, leading to the CDC recommending vaccinated people to wear masks indoors again.
10:13
Vaccinated individuals can still transmit the Delta variant, but they are less likely to get as sick as unvaccinated individuals, making Delta scarier for the unvaccinated.
14:35
The P681R mutation, also known as the permutation, optimizes the spike shape of the Delta variant, making it easier for the virus to infect cells and explaining why it spreads quickly and evades vaccines.
17:29
The Delta variant has a higher viral load, making it about two to three times as infectious as the original strain, but it does not mean you are a thousand times more likely to catch COVID from someone with Delta; however, Delta is making people more sick and those infected are twice as likely to be hospitalized compared to the older strain.
20:21
The Delta variant is more contagious and potentially more severe, but vaccinated people are still less likely to get seriously ill, and as long as a large portion of the population remains unvaccinated, the pandemic will continue and there is a possibility for the virus to evolve into worse variants.
