LIVE: Media briefing on #Ukraine, #COVID19 and other global health issues with @DrTedros twitter.com/i/broadcasts/1…
@DrTedros "The global increase in #COVID19 cases continues, driven by large outbreaks in Asia and a fresh wave in Europe. Several countries are now seeing their highest death rates since the beginning of the pandemic"-@DrTedros
@DrTedros "This reflects the speed with which Omicron spreads, and the heightened risk of death for those who are not vaccinated, especially older people"-@DrTedros #COVID19

The most burning 🔥 Questions right now:

Will #SARS2 continue to mutate to escape antibody protection? Do we need another booster? If so, what’s the next formula? For example, do we need an Omicron-specific vaccine?
1/
By the time an Omicron-specific vaccine is tested, we won’t have an Omicron wave anymore. So, is there still value in rolling it out? 2/
It all depends on how the SARS2 keep on evolving? The problem is it’s not following a fixed pattern. We know about evolutionary features of two viruses namely #flu and #measles. 3/

Development of 1st Measles💉begins in earnest in 1954. Enders' lab adapts virus to 🐔embryos & has 💉ready in '63. In '68 Hilleman et al. developed a more effective version. A 2nd dose was later recommended after the 1989 outbreak. It took until 2000 to eliminate measles, almost
20 years later than the CDC's original goal of elimination by 1982. It's still a stunning achievement we should be proud of. @AmeshAA states: "Measles is one of the most contagious infectious diseases, which means that you need more than 93% immunity to protect a population."
Measles is now considered a 💉preventable disease. Each time there has been an outbreak (largely due to returning from international travel where there were active cases) in the US, the virus was shut down by community immunity, or herd immunity.

🆕 ✨In recent years, low vaccine coverage has led to an increase in #measles cases in the US and #Europe, even after many countries had previously achieved elimination status.

Read the latest from IHME in @ThinkGlobalHlth ⤵️

In the US, nearly 1,300 #measles cases were recorded in 2019, with the vast majority occurring in tight-knit communities with low vaccination rates.
The #EuropeanUnion saw a nearly fivefold increase ⬆️ in measles since 2015, with 20,000 new cases recorded in 2019 and two nations (the #CzechRepublic & #Greece) losing their elimination status.

For something a bit different--let's talk about #measles. I published a paper about our 1989 measles outbreak at @KentState but forgot to discuss it here. It has some implications for university vaccines & vaccine acceptance then & now. A thread. /1 sciencedirect.com/science/articl…
/2 Some background. 2019 was our worst measles year in recent memory. We had 1,282 cases
24 confirmed in 31 states, with big outbreaks in NY and Washington state. Almost all cases were in the unvaccinated. We came close to losing our elimination status.
/3 2019 was a drop in the bucket compared to our last big measles outbreak, from 1989-1991. Over 55,000 cases were reported with 166 deaths. Unvaccinated individuals were one group--mostly kids under the age of 5 who hadn't yet received a dose of measles vaccine. But...

@DrTedros "Almost 2 million cases of #COVID19 were reported in Europe last week, the most in a single week in that region since the pandemic started.

Almost 27,000 deaths were reported from Europe, more than half of all COVID-19 deaths globally last week"-@DrTedros
@DrTedros "#COVID19 is surging in countries with lower vaccination rates in Eastern Europe, but also in countries with some of the world’s highest vaccination rates in Western Europe"-@DrTedros

While reported #measles cases have fallen compared to previous years, progress toward measles elimination continues to decline and the risk of outbreaks is mounting, according to a 🆕 report from @CDCgov & WHO.

👉 bit.ly/3C6gw7H Image
During 2020, more than 2⃣2⃣ million infants missed their first dose of #measles vaccine - 3⃣ million more than in 2019– creating dangerous conditions for outbreaks of this highly infectious disease to occur.

👉 bit.ly/3C6gw7H Image
Compared with 2019, reported #measles cases decreased by more than 8⃣0⃣% in 2020.

However, measles surveillance also deteriorated, with the lowest number of specimens sent for laboratory testing in over a decade.

There’s been a lot of discussion recently about #SARSCoV2 #vaccine effectiveness, hospitalisation, and the reason for increasing case numbers, in spite of our high rates of vaccination. This thread will not provide a definitive explanation for the above 1/n
However, I’m hopeful it will provide context to inform the discussion. TL:DR The vaccines are not 100% effective so our current level of uptake – measured across the entire population – will not be sufficient, in isolation, to suppress #SARSCoV2 transmission in the community 2/n
Over the last 18 months, the concept of “herd immunity” has been frequently referenced in public discourse: I prefer, and will use, the term “community level protection (CLP)”, thereby illustrating the concept that immunising the community is capable of 3/n

Due to the #COVID19 pandemic, 2⃣3⃣ million children 👦👧 missed out on basic vaccines through routine immunization services in 2020, increasing by 3.7 million and the highest number since 2009.

More data from WHO & @UNICEF 👉bit.ly/3B4150v
Without high childhood vaccination rates, countries face risks of multiple disease outbreaks. Spread of diseases like #measles, polio or meningitis could be catastrophic for countries already battling #COVID19.

👉bit.ly/3B4150v #VaccinesWork
Up to 1⃣7⃣ million children likely did not receive a single vaccine during last year.

Most of these children 👧👦 live in conflicted-affected communities, slum areas or under-served remote places. 👉bit.ly/3B4150v

A gist of what Dr #Fauci said last night in a Zoom chat abt #COVID19 & #science organised by @niemanfdn
A thread:
Asymptomatic transmission has been most worrying when it comes to the #pandemic. Interested to understand long #Covid going forward, the profound impact it can have.
#Science is a self corrected process but had been interpreted as flip-flopping. If you don't evolve with data you're doing something wrong.
People should not confuse #socialmedia for media which has no quality control. Classic #journalism hasn't changed. We are looking at a battle between distorters and truth-tellers.

"Globally, the #COVID19 pandemic continues to intensify. Cases have now increased for the 9th straight week, & deaths have increased for the 6th straight week. To put it in perspective, there were almost as many cases 🌍 last week as in the 1st 5 months of the pandemic"-@DrTedros
"It’s pleasing to see small declines in cases and deaths in several regions, but many countries are still experiencing intense #COVID19 transmission, and the situation in #India is beyond heartbreaking"-@DrTedros #InThisTogether

While immunization services begin slow recovery from #COVID19, millions of children around the 🌍🌏🌎 remain vulnerable to deadly diseases.

More info 👉bit.ly/3gEP2Pr
According to WHO data, 6⃣0⃣ mass immunization campaigns are currently postponed in 5⃣0⃣ countries, putting around 2⃣2⃣8⃣ million people - mostly children - at risk for diseases such as #measles, #YellowFever and #polio.

More info 👉bit.ly/3gEP2Pr
To support the recovery from #COVID19 and to fight future pandemics, we must ensure access to lifesaving vaccines and routine vaccination services are protected in every country in the 🌎🌏🌍.

Are the social distancing measures damaging our immune systems? Less contact = reduced infection rates.
For example, the number of reported whooping cough cases during the reporting period 2020/2021 is less than 5% of that of the previous year
1/
@PHE produce weekly updates on statutory notifiable diseases and usefully provide comparisons to previous years. As might be expected, there has been significant decline in all. A few more graphs below to illustrate this 👇

As well as whooping cough, there are significantly fewer reported cases of #meningococcal septicemia, acute #meningitis, #measles and #mumps

1/ Really great article that explains common misconceptions & myths about airborne viruses. Clear & easily readable.

Led by a #multidisciplinary slew of all-star scientists. If you trust anyone in the world on these topics, these are the people you trust.
journalofhospitalinfection.com/article/S0195-…
2/ Dispelled myths:

Myth 1: #Aerosols are droplets with a diameter < 5 μm
Myth 2: All particles > 5 μm fall within 1-2 m of the source
Myth 3: If it's short range, then it can't be airborne
Myth 4: If R0 isn't as large as for #measles, then it can't be airborne
3/ Dispelled myths:

Myth 5a: If it's #airborne then surgical #masks (or cloth face coverings) won't work
Myth 5b: The virus is only 100 nm (0.1 μm) in size so filters and masks won't work
Myth 6: Unless it grows in tissue culture, it's not infectious

Talk in the UK (& Germany & Denmark) of using just 1 #COVID19 #vaccine dose/person for now, possibly providing boosters months later, is distressing.
A quick thread follows.
1.) @Pfizer has been clear as a bell: 1 dose = 52% protection, 2 doses = 95%

bmj.com/content/371/bm…
2/ Compare those 52% vs 95% numbers to #measles. After Dose 1 a child is 69% protected against measles, but that jumps to 91% w/2nd dose. Given measles is ultra-contagious (Ro up to 18!) anything <90% is awful.

3/ In contrast, #hepatitisB vaccine offers up to 93% protection w/1 dose & 97.8% w/2 doses. ncbi.nlm.nih.gov/pmc/articles/P…
The virus is not very contagious (Ro<1), and not airborne, so a single dose of vaccination may be adequate for people who aren't sexually active.

Now #TonyFauci is addressing @WhiteHouse presser, talking about #COVID19 #vaccines & OWS.
Highly effective vaccines, "have crushed" diseases like measles and polio.
OWS has backed 6 candidate vaxes. 2 of them "extraordinarily impressive" - Moderna & Pfizer. Image
2/Fauci
Reviews data on Moderna and Pfizer vaccine data -- "almost to the level of what we see with #measles" #vaccine, 98% effective.
Only way to get an effective program is when ppl take the vaccine. There is reticence in the public. "Speed did not compromise at all the safety"
3/Fauci
"Who looked at the data?" It was an independent body -- with no allegiance to anyone. Now @FDA studying.
"We need to put to rest any concept that this was rushed in an inapprop. way."
"The cavalry is on the way."
