... unless you want some adventure,...
First off: Where will you land?
Second: Where will you bird (main areas).
As long as you don't plan to go to the real troubled areas, you should be fine, as far as my Infos go from people in Egypt. Cairo is still not a great place to be right now, of course and I don't know what the future will bring.
But for example the news of tanks rolling into Sharm: My friends there haven't seen any,...
Doesn't Hep B take 6 months to be finished (3 shots, I think).
Luxor is currently in the areas recommended to avoid, eg by FCO, but in reality if you are avoiding the main areas of protest, there likely would be no problem currently .
However, and this is the maybe that you might consider - the situation is simply unpredictable. I would imagine things will have stabilized way before April, but renewed or continued protest could have major impact on your trip - in particular relating to your flight.
If the flight operator pulls out due to unrest (and currently many have, and [charters especially] are likely to continue to do so until FCO recommendations change), you're stuffed - many carriers are compensating and you might be entitled to compensation, but don't count on it - civil unrest can be deemed force majeure. Likewise you would want to check carefully if any insurance you might have would be valid, cancellations due to force majeure may well not be covered.
If your airline does fly, but you feel it is not safe due to events happening at that time, you are simply (and quite rightly) considered a 'no show' - absolutely no chance of compensation or insurance claim.
If you worry that you may lose money or worry about the risk, I would simply choose another destination for this April - Egypt will always be there next year, plenty of other totally risk-free places elsewhere.
Since Mubarak decided to stay 'in power' things most likely will only get worse.
Come to Kuwait during Migration
Kuwait is possibly an alternative
I must admit that Mubarak staying surprised me and the repercussions of that decision could cause even more major unrest
The decision really didn't surprise me. He thinks he is god's - sorry, Allah's gift to Egypt,...
Anyhow, there sure will be more unrest and most likely worse than we've seen so far. Mubarak will rally more supporters which will in turn cause more trouble
And I agree, only time will tell what will happen down there.
Depending on where you eat, the hygiene is supposedly better here. But we honestly have had more stomach troubles here than in Egypt.
So, a tough one to answer
Power corrupts, absolute power corrupt, absolutely.
Its no suprise the he's not letting go before he has no other choice, think of Idi Amin, Saddam Hussein, etc etc Imho, Egypt will get worse before it gets better and I for one would avoid it. There's always next year!
Regarding to Reuters, Mubarak def. has resigned.
Regarding my humble opinion, he has been in Sharm since 3 weeks - the only place he feels safe
Like I said, Kuwait was more a 'not so serious' hint
Not sure what you would want to do here for a whole week
To return to the initial question: only a qualified MD can answer if you really need all these shots. Generally, tuberculosis shots are not currently recommended (as far as I know), the antibodies (if produced) are not really protective, but may well make the diagnosis of the disease more difficult so that it is more severe before you get a proper diagnosis!
Hepatitis A and update of your typhoid might very well be a good idea if you will be traveling at all (in other words also to other places), but again, consult a specialist.
