In the UK at the moment there's some controversy regarding the changing of the timing of the Covid vaccination boosters. All the vaccines I can think of that need boosters are given to babies, whose immune systems aren't fully developed yet. So they get some protection initially but need a booster when they're more mature. Are there any vaccines given to adults that actually need a booster? Was it used in the Covid trials for a good reason, or just to make doubly sure the results would be good? The information I can find online only covers the standard childhood vaccinations, and similar questions on this forum by other people over the past few years have remained unanswered.
It has been suggested by my employer that i should get the Hepatitis B vaccine to protect myself.  I have had two of the three parts, but this is the first time i have had a vaccine in more than one session.  The vaccine is in 3 doses, each around a month apart, followed up by a blood test.  Why is the Hepatitis B vaccine split into 3, any what is the blood test for at the end?
How can I avoid asking duplicate questions? WP List Table custom quick edit box - post meta data missing and columns change on submit I have extended class WP_List_Table to create a custom sortable table of posts along with a quick edit box with custom meta boxes.  The meta boxes populate and save but when I click submit the field values disappear and the defaults ( cb, title, tags, cats, etc) which are not even included in my class get added back to the column saved. This throws off the other columns on the page.  The saved custom field values return when the page is refreshed.  It seams like on submit the $post_object is missing.  I'm using a hacked get_inline_data function that includes the meta_values in my quick edit form instead of calling get_inline_data in my class.  My save function for the meta boxes:  add_action( 'save_post', 'save_inline_edit_meta' ); function save_inline_edit_meta( $post_id  ) {     global $pagenow;      if ( $pagenow == 'admin.php' ) {      if ( isset( $_POST[ 'is_quickedit' ] )  &amp;&amp; isset( $_POST[ 'standinghead' ] ) )         update_post_meta( $post_id, '_wnd_standing_head', $_POST[ 'standinghead' ] );      if ( isset( $_POST[ 'is_quickedit' ] )  &amp;&amp; isset( $_POST[ 'headline' ] ) )         update_post_meta( $post_id, '_wnd_alt_title', $_POST[ 'headline' ] );      if ( isset( $_POST[ 'is_quickedit' ] )  &amp;&amp; isset( $_POST[ 'deck' ] ) )         update_post_meta( $post_id, '_wnd_deck', $_POST[ 'deck' ] );     }   return $post_id;  }   My Javascript save function:  save : function(id) {         var params, fields, page = $('.post_status_page').val() || '';          if ( typeof(id) == 'object' )             id = this.getId(id);         $('table.widefat .inline-edit-save .waiting').show();         params = {             action: 'inline-save',             post_ID: id,             post_type: 'post',             edit_date: 'true',             post_status: page         };         fields = $('#edit-'+id+' :input').serialize();         params = fields + '&amp;' + $.param(params);          $.post('admin-ajax.php', params,             function(r) {                 $('table.widefat .inline-edit-save .waiting').hide();                  if (r) {                     if ( -1 != r.indexOf('&lt;tr') ) {                         $(inlineEditPost.what+id).remove();                         $('#edit-'+id).before(r).remove();                         $(inlineEditPost.what+id).hide().fadeIn();                     } else {                         r = r.replace( /&lt;.[^&lt;&gt;]*?&gt;/g, '' );                         $('#edit-'+id+' .inline-edit-save .error').html(r).show();                     }                 } else {                     $('#edit-'+id+' .inline-edit-save .error').html(inlineEditL10n.error).show();                 }             }         , 'html');         return false;     }, How do I print my Java object without getting "SomeType@2f92e0f4"? Serializing anonymous delegates in C# Does there exist an automorphism of $\mathbb{C}$ that does not keep $\mathbb{R}$ fixed? On the proof that the product of diagonal matrices is a diagonal matrix? Let $A [a_{i,j}]$  and $B =[b_{ij}]$   be two diagonal matrices in   $M_n(F)$. Let $i \ne j \in \left\{1, \ldots, n \right\}$. Using the   product rule, we obtain      $$(AB)_{ij} = \sum_{k=1}^{n} a_{ik}b_{kj}$$      We claim that $a_{ik}b_{kj} =0$ for all $k \in \left\{1, \ldots, n \right\}$ thus $(AB)_{ij}=0$ for all $i \ne j$ and $AB$ is diagonal. To    prove the claim, note that since $i \ne j$ , we have $i \ne k$ or $    k\ne j$. Thus either $a_{ik} = 0$ (since $A$ is diagonal) or $b_{kj} =  0$ (since $B$ is diagonal), thus in all cases $a_{ik}b_{kj}=0$ and the   claim is proved.   Where does the bit "we have $i \ne k$ or $k\ne j$" come from? I understand that since $i \ne j$, and $k$ and $j$ run over the same set of natural numbers, we also have $i \ne k$. But the "or $k \ne j$" baffles me. I understand that $k \ne j$ implies that we can have $i=k$. But that's from the other direction ($\Longleftarrow).$  Also, when it says $a_{ik}=0$ or $b_{kj}=0$ it's talking about when $i \ne k$ or $k \ne j$ right? Many thanks. Prove $ \sin(A+B)\sin(A-B)=\sin^2A-\sin^2B $ How would I verify the following double angle identity. $$ \sin(A+B)\sin(A-B)=\sin^2A-\sin^2B $$ So far I have done this. $$ (\sin A\cos B+\cos A\sin B)(\sin A\cos B-\cos A\sin B)  $$But I am not sure how to proceed. When you click on the Opportunities tab, (assuming you haven't modified standard salesforce layout), you see a "Recent Opportunities" list. At the top of the list, there is a "New" button.

Show that the congruence $x^{p-1} \equiv 1 \pmod {p^2}$ has precisely $p-1$ solutions modulo $p^2$ Let $p$ be a prime number.

Show $\rho(g)$ is a scalar multiple of the identity matrix $I$.   I think I have it, here is my solution:  Since $\rho(g) \in Hom_G(\mathbb{C}, \mathbb{C})$ and $\rho$ is irreducible, consider a nonzero eigenvalue of $\rho(g)$, say $\lambda$, we have $\rho(g) -\lambda $ is a zero map by Schur's lemma, as the map contains a non-trivial kernel (i.e. the eigenvectors associated to $\lambda$ are in the kernel).  But I didn't use the condition that  $g\in Z(G)$, so are there something wrong with my solution? Making pen and ink corrections on a UK visa form?

The Nazgul are afraid of fire, but can they be harmed by it? When Aragorn and the Hobbits are on Weathertop, just after seeing the Nazgul below them and prior to inflicting Frodo's knife wound, Aragorn says the following:     Sauron can put fire to his evil uses, as he can all things, but these   Riders do not love it, and fear those who wield it. Fire is our friend   in the wilderness.   Is there any mention as to whether fire can actually cause harm to the Nazgul and if not, is there a specific reason for their fear of it?

I received an email this morning stating that my Wordpress site had been automatically updated to the latest version. I knew about the feature but I've always wondered exactly how it works.  PHP isn't a permanently-running process: it only runs when requested. So as far as I can tell, Wordpress can only update itself when someone loads a web page. But the update process is not instantaneous, so surely a user visiting the site would have a really slow page load.  Is there a different trick they use for automatic updates?
