Yes, the vaccines ARE effective against the Delta variant. Yes, you will want both doses for maximum protection. Yes, they’re effective against preventing symptomatic infection, severe disease, AND hospitalization. Several studies have proven this now. Stop the misinformation.
Also, yes, this does include Johnson & Johnson. Why are variants unlikely to FULLY evade vaccine-induced immunity?
•Vaccines are polyclonal (Abs)
•CD8+ T-cells covering 52 epitopes across the spike protein
•CD4+ T-cells covering 23 epitopes across the spike protein
Remember, there has yet to be a variant that isn’t susceptible to the vaccines. If none of the articles I have listed above are of interest to you, please refer to the various studies I have highlighted in my threads. Sources and links are always in the last tweet of my threads.

An analysis of ~250,000 in Canada found two doses of any of the three COVID-19 vaccines (Moderna, Pfizer, AstraZeneca) led to strong protection from infection, hospitalization, AND death -even against Delta- REGARDLESS of the vaccination combination and showed NO signs of waning.
Preliminary data from researchers at the British Columbia Centre for Disease Control (BCCDC) and the Quebec National Institute of Public Health (INSPQ) shows the decision to vaccinate more Canadians sooner by delaying second shots by up to four months saved lives.
The researchers excluded long-term care residents from the data, who are generally at increased risk of hospitalization and death from COVID-19, in order to get a better sense of vaccine effectiveness in the general population. Needless to say the results were exceptional. Image

“Breakthrough” infections DO NOT mean vaccines don’t work. Remember, they are preventives, NOT cures. One can still contract COVID once vaccinated. As long as that vaccine is preventing you from facing severe disease and worse, it IS working and doing what it was designed to do.
Regarding the concerns about waning immunity. Please remember, this is likely referring to infection. NOT effectiveness against symptomatic infection, NOT effectiveness against severe illness. While neutralizing antibodies decrease over time (as they ARE supposed to) protective
immunity provided by memory B-cells and T-cells is STILL present. Remember: Immunological memory consists of antibodies, memory B-cells, memory CD8+ T-cells, and memory CD4+ T-cells. These responses give us enduring protection even against newly emerging SARS-CoV-2 variants.

“The vaccines don’t work- look at Singapore.” Alright, let’s do it.

Cases are at record highs due to Delta, however, OVER 98% of Singapore’s vaccinated cases are MILD or have NO symptoms. In addition, the nation has had VERY FEW deaths despite a surge in cases.

I’m not done.🧵
As of Tuesday, 83% of Singapore’s population is considered to be fully vaccinated. TO NOTE: Singapore recently transitioned away from a Zero COVID approach. The rise in cases upon attempting to reopen was to be expected as part of attempting to “live” with the virus and reopen.
According to their MOH, over the last 28 days, of the 43,610 infected individuals, 98.3% are MILD or have NO symptoms, 1.4% required oxygen supplementation, 0.1% required ICU care, and 0.2% had died. moh.gov.sg/news-highlight….

This has not been shared widely in the media so let’s fix that. COVID-19 is now in retreat in the United States, the United Kingdom, AND Worldwide. Worldwide, cases have fallen MORE THAN 30% since late August and weekly deaths have fallen MORE THAN 15%. It gets better. Read on.🧵
•U.S. cases and hospitalizations have fallen 35% and 25% respectively since September 1st.
•Daily deaths in the U.S. have fallen 10% since September 20th. It is the FIRST sustained decline in deaths since the early summer.
•Deaths in the U.K. have fallen 21% since their- ImageImage
September peak.
•Hospitalizations in the U.K. are down 28% since their September peak.
•The pattern has also been evident within countries, including India, Indonesia, Thailand, Britain, France, and Spain. In each of them, the Delta variant led to a surge in cases lasting-

An analysis of an outbreak of the Delta variant at nine summer youth camps in the United States shows there was NO further transmission to fully vaccinated individuals AND there was NO further transmission from breakthrough cases. Vaccination stopped the train of transmission. 🧵
This case study assessed the number of COVID-19 cases and potential secondary spread among 7,173 staff members and campers from 50 states, 13 countries, and U.S. military overseas bases at nine independently operated U.S. summer youth camps affiliated with the same organization.
Some considerations to keep in mind: some members of these groups WERE NOT eligible for COVID-19 vaccination. Three of the nine cases occurred in vaccinated staff members and six in unvaccinated campers aged 8–14 years. It is ALSO important to note that at some camps physical

So, not COVID-19 related, however, this is really exciting news I wanted to share. Phase I trials of Moderna's HIV vaccine candidate, mRNA-1644, which uses the same mRNA technology as our COVID-19 vaccine, is expected to begin clinical trials this month!
Approximately 38 million people worldwide are currently living with HIV with 1.2 million in the U.S. Approximately 2 million new infections of HIV are acquired worldwide every year and approximately 690,000 people die annually due to complications from HIV/AIDS.
mRNA-1644 is a novel approach to HIV vaccine strategy in humans designed to elicit broadly neutralizing HIV-1 antibodies (bNAbs). The Phase 1 study for mRNA-1644 will use iterative testing to validate the approach and antigens and multiple novel antigens will be used
