Majority of Americans intend to get vaccinated; all 50 states announce when they plan to open vaccine eligibility: Live COVID-19 updates – USA TODAY

Relatives and friends of Britons who lost their lives to the coronavirus are drawing thousands of hearts on a wall opposite the Parliament in London as a memorial to the 145,000 victims. 

“Each heart represents someone who was loved. Someone who was lost too soon to Covid-19,” the organizers, Covid-19 Bereaved Families for Justice UK, said on their crowdfunder page. “As bereaved family and friends this is how we choose to remember.”

Each heart is being drawn by hand, and the National Covid #MemorialWall will have drawn more than 145,000 of them. The palm-sized hearts will cover a a 6-foot-tall wall the length of more than five football fields. Hearts will continue to be added until the pandemic ends and the deaths stop, the group says.

“Like the scale of our collective loss, this memorial is enormous,” he group said. “We hope everyone in the country will be part of this effort, and together we can share our grief through this overwhelming display of love.”

Hospital staff from St Thomas' Hospital watch from the top of the wall as members of bereaved families paint red hearts on the COVID-19 Memorial Wall opposite the Houses of Parliament on the Embankment in London, Monday March 29, 2021.

Pfizer says its vaccine is safe for kids 12 to 15 years old

The COVID-19 vaccine from drug company Pfizer and its German partner BioNTech vaccine is safe for and extremely effective in adolescents, according to a company-sponsored study released early Wednesday. In adolescents 12 to 15 years old, vaccination led to a higher protective antibody response than in adults and was seen to be 100% effective against symptomatic disease, the study of 2,260 adolescents found. The two-shot Pfizer-BioNTech vaccine had been authorized for use in those 16 and up based on previous trials, but not in younger adolescents.

Last week, the companies began testing their vaccine in children ages 5 to 11; next week, they will begin testing in ages 2 to 5, and later will look at children 6 months to 2 years.

US tops 12K known COVID variant cases

The United States has reported more known coronavirus variants in the last week —nearly 4,300 — than it reported through the middle of March, a USA TODAY analysis of CDC data shows.

Tuesday night’s tally reflected more than 1,000 new cases just since Sunday’s report. The U.S. now has 12,053 known cases of variants that can spread COVID-19 more easily, dodge some treatments and immunities, or both.

California alone reported 289 new variant cases Tuesday, bringing it up to 865 known cases. Most of those are of B.1.1.7, a variant first seen in the United Kingdom. But California’s P.1 case count also exploded, moving from seven known cases on Sunday to 33 known cases Tuesday. P.1 was first seen in Brazil.

Massachusetts reported 266 new cases, bringing its total to 732.

Several states that hadn’t had much of a known variant problem suddenly have much larger problems. West Virginia went from just three known variant cases on Sunday to 53 on Tuesday, while Nevada went from 11 cases on Sunday to 63 cases on Tuesday. Idaho jumped from 18 to 32.

Ohio reported its first two cases of the B.1.351 variant first seen in South Africa.

Most Americans want vaccine or are already vaccinated

The majority of U.S. adults say that they’ve either being vaccinated for COVID-19 or intending to do so as soon as possible, and that number continues to rise. That’s according to a new survey from nonpartisan health foundation Kaiser Family Foundation, which puts that number at 61% of respondents while the share that responded said they’re taking a “wait and see” approach has shrunk to 17%. 

The new developments come as average daily reported cases are up 10% compared to a week earlier, data from the Centers for Disease Control and Prevention shows. And as COVID-19 cases creep up again across the country, federal officials and epidemiologists say they’re worried we could hit another tipping point, leading to a fourth significant surge of infections, hospitalizations and deaths. Read more here.

Nations challenge WHO report on coronavirus origins

The U.S. and a dozen other countries issued a rare joint statement on Tuesday questioning the validity of a World Health Organization study into the origins of the coronavirus, which was first detected in Wuhan, China, and has now killed 2.8 million people across the globe.

“We support a transparent and independent analysis and evaluation, free from interference and undue influence, of the origins of the COVID-19 pandemic. In this regard, we join in expressing shared concerns regarding the recent WHO-convened study in China,” reads the statement, which was issued by the U.S. State Department in coordination with a raft of other governments, including Australia, Canada, and the United Kingdom.

The statement included strong support for the WHO and did not directly blame China for interfering with the scientific probe. But it said health experts were delayed in studying the origins of the virus and that even when granted access, they were denied “complete, original data and samples.”

“The mission of the WHO is critical to advancing global health and health security,” the statement said. “Scientific missions like these should be able to do their work under conditions that produce independent and objective recommendations and findings.”

The WHO’s director, Tedros Adhanom Ghebreyesus has also highlighted China’s lack of cooperation.

“I do not believe that this assessment was extensive enough,” he said. “Further data and studies will be needed to reach more robust conclusions.”
